RFQ ListingPower Management ICs
The DRV8311PRRWR is a Texas Instruments 3-phase brushless-DC motor driver integrating three half-bridge MOSFETs, gate drive and three current-sense amplifiers in a single 24-pin WQFN. Driving 3 V to 20 V rails with 5 A peak current and a 6x/3x PWM or tSPI interface, it shrinks BLDC control loops for drones, robotics and small appliances with no external sense resistors.
