Table 2. Block description

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.

Undervoltage

Shuts down the device for battery voltage lower than 4 V.

High-side and low-side clamp voltage

Protect the high-side and the low-side switches from the

high voltage on the battery line.

High-side and low-side driver

Drive the gate of the concerned switch to allow a proper

Ron for the leg of the bridge.

Current limitation

Limits the motor current in case of short circuit.

High-side and low-side overtemperature

protection

In case of short-circuit with the increase of the junction

temperature, it shuts down the concerned driver to prevent

degradation and to protect the die.

Low-side overload detector

Detects when low side current exceeds shutdown current

and latches off the concerned Low side.
