Pin Assignments (Repeated) Pin Definitions Name Pin Description ENA Enable Input for Channel A. Pull pin LOW to inhibit driver A. ENA has TTL thresholds for both TTL and CMOS INx threshold. ENB Enable Input for Channel B. Pull pin LOW to inhibit driver B. ENB has TTL thresholds for both TTL and CMOS INx threshold. GND Ground. Common ground reference for input and output circuits. INA Input to Channel A. INA+ Non-Inverting Input to Channel A. Connect to VDD to enable output. INA- Inverting Input to Channel A. Connect to GND to enable output. INB Input to Channel B. INB+ Non-Inverting Input to Channel B. Connect to VDD to enable output. INB- Inverting Input to Channel B. Connect to GND to enable output. OUTA Gate Drive Output A: Held LOW unless required input(s) are present and VDD is above UVLO threshold. OUTB Gate Drive Output B: Held LOW unless required input(s) are present and VDD is above UVLO threshold. OUTA Gate Drive Output A (inverted from the input): Held LOW unless required input is present and VDD is above UVLO threshold. OUTB Gate Drive Output B (inverted from the input): Held LOW unless required input is present and VDD is above UVLO threshold. P1 Thermal Pad (MLP only). Exposed metal on the bottom of the package; may be left floating or connected to GND; NOT suitable for carrying current. VDD Supply Voltage. Provides power to the IC.
