Overview
The DRV8313RHH, produced by Texas Instruments, is a 2.5-A triple 1/2-H bridge driver IC designed for driving three-phase brushless DC motors, solenoids, and other loads. This device integrates three individually controllable half-H-bridge drivers, each consisting of N-channel power MOSFETs in a 1/2-H-bridge configuration. It features a wide operating supply-voltage range of 8-V to 60-V, making it versatile for various motor drive applications. The DRV8313RHH also includes built-in protection circuits for undervoltage, charge pump faults, overcurrent, short circuits, and overtemperature, with fault conditions indicated by the nFAULT pin.
