DRV8329/DRV8329-Q1 Three-phase BLDC Gate Drivers Texas Instruments DRV8329/DRV8329-Q1 Three-phase BLDC Gate Driver provides three devices, each capable of driving high-side and low-side N-channel power MOSFETs. The DRV8329 generates the correct gate drive voltages using an internal charge pump and enhances the high-side MOSFETs using a bootstrap circuit. Additionally, a trickle charge pump is included to deliver a 100% duty cycle.
