データシート
 

概要

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.

For all available packages, see the orderable addendum at the end of the data sheet.
