The DRV8313 provides three individually controllable half-H-bridge drivers. It is intended to drive a three-phase brushless dc motor, though it can also be used to drive solenoids or other loads. Each output driver channel consists of N-channel power MOSFETs configured in a half-H-bridge configuration. The design brings the ground terminals of each driver to pins, to allow one to perform current sensing on each output.
Current-limit circuitry or other functions are possible uses of an uncommitted comparator.
The DRV8313 can supply up to 2.5-A peak or 1.75-A rms output current per channel (with proper PCB heatsinking at 24 V and 25°C) per half-H-bridge.
The device provides internal shutdown functions for overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature.
The DRV8313 comes in a 28-pin HTSSOP PowerPAD package.
