Features :

1. PWM capability of up to 25 kHz combined with active freewheeling.
2. Switched mode current limitation for reduced power dissipation in overcurrent.
3. Status flag diagnosis with current sense capability.
4. Overtemperature shut down with latch behavior.
5. Overvoltage lockout.
6. Undervoltage shut down.
7. Driver circuit with logic level inputs.
8. Adjustable slew rates for optimized EMI.
9. 74AHC244 Schmitt-trigger Octal buffer/line driver for ESD protection (Inputs accepts voltages higher than VCC).

Input port:

1. RPWM: forward level or PWM signal input, active high.
2. LPWM: Reverse level or PWM signal input, active high.
3. R_EN: forward drive enable input, high-level enable, low level off.
4. L_EN: Reverse drive enable input, high-level enable, low level off.
5. R_IS: forward drive current alarm output.
6. L_IS: Reverse drive current alarm output.
7. VCC: +5 V power output, 5V power supply connection with the microcontroller.
8. GND: signal common low end.
