AGND
Open drain output, active low. Is set according to the truth table. When a fault appears, SF changes
typically in less than 100 ms.

When not connected or connected to GND, a stored failure will be reset by change of the voltage-
level on DI1 or DI2.
8
COD
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.
H-Bridge outputs with integrated free-wheeling diodes.
