Name

Type

Function

IN1A

Logic input

Bridge A logic input 1.

IN2A

Logic input

Bridge A logic input 2.

45, 46

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.

2, 3

OUT1A

Power output

Bridge A output 1.

6, 31

GND

Signal ground terminals. These pins are also used for heat dissipation

toward the PCB.

10, 11

OUT1B

Power output

Bridge B output 1.

OCDB

Open-drain output

Bridge B overcurrent detection and thermal protection pin. An internal

open-drain transistor pulls to GND when overcurrent on bridge B is

detected or in case of thermal protection.

15, 16

SENSEB

Power supply

Bridge B source pin. This pin must be connected to power ground

directly or through a sensing power resistor.

IN1B

Logic input

Bridge B input 1
