Description

9, 10, 11, 12

Metal slug

PGND

Power Ground. All the ground are connected together, they should be connected as short as

possible on the PCB.

1AGND

Analog ground. All the ground are connected together, they should be connected as short as

possible on the PCB.

2Output

Status flag (SF)

Open drain output, active low. Is set according to the truth table. When a fault appears, SF changes

typically in less than 100 ms.

3,13

18, 19

Inputs IN1, IN2,

DI1, DI2, COD

Voltage controlled inputs with hysteresis

8COD

When not connected or connected to GND, a stored failure will be reset by change of the voltage-

level on DI1 or DI2.

When connected to VCC, the disable Pin DI1 and DI2 are inactive. A stored failure will be reset by

change of the voltage-level on IN1 or IN2.

6, 7, 14, 15

OUT1, OUT2

H-Bridge outputs with integrated free-wheeling diodes.
