3 Description

The DRV8313 provides three individually controllable

half-H-bridge drivers. The device is intended to drive

a three-phase brushless-DC motor, although it can

also be used to drive solenoids or other loads. Each

output driver channel consists of N-channel power

MOSFETs configured in a 1/2-H-bridge configuration.

Each 1/2-H-bridge driver has a dedicated ground

terminal, which allows independent external current

sensing.

An uncommitted comparator is integrated into the

DRV8313, which allows for the construction of

current-limit circuitry or other functions.

Internal protection functions are provided for

undervoltage, charge pump faults, overcurrent, short

circuits, and overtemperature. Fault conditions are

indicated by the nFAULT pin.
