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