# STSPIN9P23TR (Component)

## Description

Advanced Full\-Bridge Motor Driver IC – 75 V high\-current full\-bridge motor driver with integrated power MOSFETs for brushed DC, brushless DC \(BLDC\), and bipolar stepper motor control\. Operates from a 7 V to 75 V supply, delivers up to 6 A continuous output current, and features two integrated half\-bridges with PWM and logic control inputs\. Includes an integrated charge pump for 100% duty\-cycle operation, current\-sense amplifier, programmable current limiting, adjustable slew\-rate control, open\-load detection, undervoltage lockout \(UVLO\), overcurrent protection, and thermal shutdown\. Designed for motor applications up to 500 W, operates over a −40°C to \+150°C junction temperature range, and is housed in a 55\-pin VFQFPN \(9 × 7 mm\) package\.
