製品概要
概要
The VNF9D1M2Q is a device made using STMicroelectronics VIPower technology. It is intended for driving resistive, inductive or capacitive loads directly connected to ground.
The device is protected against voltage transient on VCC pin. Programming, control and diagnostics are implemented via the SPI bus. A digital current sense feedback and an STi²Fuse digital current sense feedback for each channel are provided through two independent integrated 10-bit ADCs per channel. Dedicated trimming bits adjust the ADC reference current. The device is equipped with 2 outputs controllable via SPI and/or with two dedicated direct inputs.
Real time diagnostic is available through the SPI bus (communication error, overtemperature, harness protection, overload protection, VCC and output voltage monitoring, TC monitoring). Output overcurrent detection protects the device in overload condition. Thermal shutdown is configured as latched off.
The VNF9D1M2Q embeds the ST proprietary I²t functionality, featuring an intelligent circuit breaking aimed at protecting PCB traces, connectors and wire harness from overheating, with no impact on load transients like inrush currents and capacitance charging. This function is set by two parameters, called INOM and tNOM: there are 3 dedicated bits, per each parameter, to set respectively INOM (nominal current) and tNOM (nominal timing). The I²t curve parameters can be individually set per each channel. The default values of these two parameters can be programmed twice using dedicated OTPs. The selection of default I²t configuration from OTPs for all channels is defined by the I2TCFGINIT in the ITCNTSR register. Further information about the OTP programming mode is provided in the dedicated user manual UM3275 (OTP programming for STi²Fuse devices).
The device enters a limp-home mode in case of reset of digital memory, watchdog monitoring time-out event or when LH (limp-home) pin is set to high. In limp-home mode each output is controlled by dedicated direct inputs. Emergency pins allow a rapid switch-off of the output channels in case of critical events in normal operation mode bypassing SPI control.
During standby mode, the device is able to support the parking mode functionality. In case the OUTPUT pin is pulled up to battery by an external secondary switch (for instance, the L99SP08 which is delivering the requested current to the load), the device offers a very low current consumption.
For further information refer to the application note AN6025 - Interaction of L99SP08 with single (VNF9SxQ) and dual (VNF9DxQ) hybrid eFuses.
