IN1A

Logic input

Bridge A logic input 1.

IN2A

Logic input

Bridge A logic input 2.

SENSEA

Power

supply

Bridge A source pin. This pin must be

connected to power ground directly or

through a sensing power resistor.

OCDA

Open drain

output

Bridge A overcurrent detection and thermal

protection pin.An internal open drain

transistor pulls to GND when overcurrent

on bridge A is detected or in case of

thermal protection.

1, 18, 19, 36

GND

Signal ground terminals. In Power DIP and

SO packages, these pins are also used for

heat dissipation toward the PCB.
