Name

Description

Logic control

Allows the turn-on and the turn-off of the high side and the low side switches

according to the truth table

Overvoltage +

undervoltage

Shuts down the device outside the range [5.5V..16V] for the battery voltage

High side and low

side clamp voltage

Protects the high side and the low side switches from the high voltage on the

battery line in all configurations for the motor

High side and low

side driver

Drives the gate of the concerned switch to allow a proper RDS(on) for the leg of

the bridge

Linear current limiter

Limits the motor current by reducing the high side switch gate-source voltage

when short-circuit to ground occurs

Overtemperature

protection

In case of short-circuit with the increase of the junction’s temperature, shuts

down the concerned high side to prevent its degradation and to protect the die

Fault detection

Signals an abnormal behavior of the switches in the half-bridge A or B by

pulling low the concerned ENx/DIAGx pin
