Overview
The DRV8313RHHR, produced by Texas Instruments, is a 2.5-A triple half-H bridge driver IC designed to drive 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. It features a wide operating supply voltage range of 8-V to 60-V, making it versatile for various motor drive applications. The DRV8313RHHR also includes built-in protection circuits, a sleep mode for standby operation, and an uncommitted comparator for current limit or other functions.
