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.
