DIA57100

The device is a fully integrated H-bridge motor driver intended for a wide range of automotive applications. The design of monolithic die in a power package offers better robustness and higher reliability. The direction and brake operation of the motor are simply controlled by applying digital signals to the INA and INB. The CS pin allows to monitor the motor current by delivering a current proportional to the motor current value, and it also develops a voltage flag for a failure on the relevant output in the ON state as well as the OFF state. The independent PWM pin, up to 20 kHz, allows to control the speed of the motor easily in all possible conditions. In all cases, a low level state on the PWM pin turns off both the LSA and LSB switches.
