The STEVAL-IFN004V1 demonstration board is based on STMicroelectronics’ STM8S105 microcontroller and the DMOS fully integrated three-phase motor driver L6230 implementing 6-step scalar control of a BLDC motor.

The board is designed as an evaluation environment for motor control applications in the range of 8 V - 48 V of DC bus voltage and up to 35 W, exploiting the embedded features of the STM8S105. This microcontroller includes internal 2 KB SRAM and 128 KB Flash, and SWD debugging. The L6230 DMOS driver features 2.8 A output peak current, non-dissipative overcurrent detection/protection, cross-conduction protection, internal comparator used for cycle-by-cycle current limitation/regulation, thermal shutdown and undervoltage lockout.

The STEVAL-IFN004V1 is provided with a specific BEMF detection network with dynamic method selection.

Offering dedicated hardware evaluation features, the STEVAL-IFN004V1 board is designed to help developers evaluate the device and develop their own applications. The STEVAL-IFN004V1 can be used together with the STM8Sxxx three-phase BLDC motor control software library and constitutes a cost-effective complete motor control evaluation and development platform.

The STEVAL-IFP001V1 demonstration board implements the functions of the VN808CM-E, an 8-channel high-side driver with CMOS compatible voltage levels in industrial applications, and is developed using VIPower M0-3 proprietary technology. The VN808CM-E completes the series of octal high-side drivers for the factory automation market.

It is intended for driving any kind of load with one side connected to ground and can be driven by using a 3.3 V logic supply. Active current limitation, combined with thermal shutdown and automatic restart, protects the device against overload.

The STEVAL-IFP001V1 is compliant with international electromagnetic compatibility (EMC) specifications as well as EMC immunity proof 4 kV level EFT (IEC 61000-4-4), and 2 kV voltage surge (IEC 61000-4-5), and has been tested at different typical ambient temperatures. It is suitable for use in programmable logic controllers to produce the related digital outputs according to IEC standards.

The STEVAL-IFP001V1 is also based on the SM15T33A, a unidirectional Transil™ diode.

The purpose of this demo board is to evaluate the features of the PCLT-2A sensor input termination.

The PCLT-2A is a dual termination device for the front-end of a 24 V DC digital input module.

Composed of an input-voltage protection, a serial current-limiter circuit and an output driver, each channel circuit terminates the connection between a high-side proximity sensor and the I/O module. Because of its IEC type programmability and the isolated/non-isolated output options, the PCLT offers a flexible and easy-to-design solution for highly integrated I/O modules.

The STEVAL-IFP010V3 demonstration board is based on the VNI2140J, a monolithic device designed using ST’s VIPower technology for driving two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents a drop in system power supply if the load is shorted. A built-in thermal shutdown protects the chip from overtemperature and short-circuit conditions. During an overload condition, the channel turns off and back on automatically in order to maintain the junction temperature between TTSD and TR. If this condition causes the case temperature to reach TCSD, the overloaded channel is turned off and will restart only when the case temperature has decreased down to TCR.

If more than one channel is in overload, the TCSD restart will not be simultaneous in order to prevent high peak current from the supply. Non-overloaded channels continue to operate normally. The open-drain diagnostic outputs indicate overtemperature conditions and open load in the off-state.

The STEVAL-IFP016V2 IO-Link communication master transceiver demonstration board is based on the L6360, monolithic IO-Link master port. A modular and customizable application that interfaces externally with the microcontroller. The purpose of the board is to demonstrate the capability of the L6360 monolithic IO-Link master, as communication transceiver for multiple I/Os.

The board uses input signal from the microcontroller and outputs the 24 V required for industrial applications.

The board demonstrates that the L6360 is both IO-Link master port mode and standard IO mode compliant.

The interface is compatible with the STEVAL-PCC009V2 and STEVAL-PCC009V1 EMC-immune application against ESD, burst, surge, RF noise, etc., according to IEC61000-4-2, IEC61000-4-4, IEC61000-4-5, and IEC61000-4-6 standards.

A large GND area on the printed circuit board has been designed in order to minimize noise and ensure good thermal performance.

The small size of the L6360 package with a reduced pin number, along with the small size of the application area, allow the user to work in applications where space constraint is critical. The L6360 is a monolithic IO-Link master port, compliant with PHY2 (3 wires) supporting COM1 (4.8 kbaud), COM2 (38.4 kbaud) and COM3 (230.4 kbaud) modes. The output stage (high-side, low-side or push-pull) as well as the cutoff current, cutoff current delay time, and restart delay, are programmable by I2C protocol.

The cutoff current and cutoff current delay time, combined with the thermal shutdown and automatic restart, protect the device against overload and short-circuit. The output stages are able to drive resistive, inductive and capacitive loads. Fast demagnetization is able to dissipate the energy stored in the inductive loads.

The STEVAL-IFP019V1 demonstration board shows the features of the VNI4140K-32 quad high-side smart-power solid-state relay.

The application offers robustness and complies with EMC industrial standards. It implements short-circuit/overload protection and also thermal management, achieving best-in-class MTBF values. The reference design is suitable for use in programmable logic controllers (PLCs) as well as to drive generic loads which require up to 1 A of nominal current (the typical current limitation is 1.1 - 2.6 A). Thanks to the very low R_DS(on)(only 80 mΩ typical @ 25 °C per channel) the device allows very low power consumption during operation and for this reason it offers an ideal solution for IP65 / IP67 requirements. The VNI4140K-32 is compliant with IEC 61131-2 (international standard for programmable controllers).

The STEVAL-IFP020V1 demonstration board is based on the L6370Q, a single-channel high-side driver chip intended for driving resistive, inductive or capacitive loads in an industrial environment. It provides an embedded fast demagnetization feature for inductive load switch-off.

The device evaluates load disconnection (during channel on-state), output short to V_CCor GND, overtemperature, undervoltage of supply voltage, and provides feedback to a control unit.

Integrating an extensive set of electrical protections makes the application safe and reliable for use in harsh conditions.

The STEVAL-IFP020V1 demonstration board is an example of application design using the L6370Q. It is used to guide the designer in choosing external components for applications while providing an appropriate PCB design.

The STEVAL-IFP021V1 demonstration board is based on the STEF05 and STEF12 electronic fuses (E-Fuses).

It is designed to help users evaluate the benefit of the complete protection offered by the E-Fuse family and to customize their own application.

The E-Fuse family of hot-swap converters is designed to replace the mechanical fuses on low voltage power lines.

The STEF05 and STEF12 are integrated electronic fuses optimized for monitoring output current and input voltage.

Connected in series to the 5 V/12 V rails, they are capable of protecting the electronic circuitry on the output from overcurrent and overvoltage.

The turn-on time is programmable by means of an external capacitor, allowing control of the inrush current at startup and during hot-swaps.

When an overload condition occurs, the E-Fuse limits the output current to a predefined safe value. If the anomalous overload condition persists, it goes into an open state, disconnecting the load from the power supply.

If a continuous short-circuit is present on the board, when power is re-applied the E-Fuse initially limits the output current to a safe value, and then again goes into an open state.

Both devices are equipped with a thermal protection circuit.

The intervention of the thermal protection is signaled to the board monitoring circuits through a signal on the enable/fault pin that can be connected to other parts belonging to the same family to cause a simultaneous shutdown during failure events.

Unlike mechanical fuses, which must be physically replaced after a single event, E-Fuses do not degrade in their performance after short-circuit/thermal protection interventions and can be reset either by re-cycling the supply voltage or by using the enable pin.

In run mode, events such as key press (matrix, special function or dedicated keys), rotator controller, power mode, etc. are captured and displayed on the LCD screen and in the scan window of the PC GUI.

For interfacing with the PC GUI, the application layer is built above the USB core library, making the USB interface hardware control transparent for developers.
