概要
The STSPIN9P series is an extremely flexible platform that supports a wide range of low-voltage motors with power ratings up to 500 W, including stepper, brushed, and brushless DC motors.
Thanks to the integration of low RDS(ON) MOSFETs (16 mΩ or 27 mΩ depending on the model), the BOM space saving compared to discrete solutions is significant.
The supply voltage is wide, ranging from 7 to 75 V. The series offers a set of pin-to-pin compatible half-bridge and full-bridge topologies, enabling coverage of a broad variety of applications.
The STSPIN9P1 sub-series includes pin-to-pin compatible half-bridge devices. Components in the STSPIN9P1 series differ in RDS(ON), driving mode, and control features to enable the adoption of a tailored solution for each specific application.
Despite their topological simplicity, the devices integrate a wide set of functional blocks and advanced features.
All versions integrate regulators making the device fully self-supplied. A charge pump allows unlimited high-side on time.
The integrated AFE, composed of a differential amplifier and a comparator, is designed to amplify the signal from a shunt resistor and compare it to a reference.
In case of versions with integrated current limiter, the comparator output is used to implement a fixed off time or a PWM trimming control strategy, otherwise it is only available for the application on the COUT open-drain output.
All devices in the STSPIN9P series feature the adjustable slew rate, enabling optimization of the EMI/efficiency trade-off. This capability improves overall performance and accelerates customer design qualification.
The devices are also fully protected thanks to UVLO (overcurrent protection and thermal shutdown). Additionally, open-load detection verifies proper motor connection when the power stage is disabled, providing dedicated signaling on the nOL output.
The STSPIN9P1 products come in a compact 7x7 QFN package.
