1. Describe

The device is a full-bridge motor driver Suitable for a wide range of automotive applications. this The device adopts dual monolithic high side driver and two low-side switches. Both switches are designed to use STMicroelectronics' well-known and proven Proprietary VIPower® M0-7 technology that allows Efficient integration on the same mold With smart power MOSFETs signal/protection circuit. three dead Electrically assembled in SO-16N package Isolated lead frame. In addition, its fully symmetrical mechanical design Allows for superior manufacturability at the board level. The input signals INA and INB can be directly Connect the microcontroller to select the motor direction and braking conditions. SEL0 pin is Information that can be used to resolve available CS to microcontroller. CS pin allows Monitor the motor current by providing a The current is proportional to the motor current value. PWM, up to 20 kHz, allows control The speed of the motor under all possible conditions. In all case, a low state on the PWM pin turns off LSA and LSB switches.
