DRV8332DKDR

Full Half-Bridge (H Bridge) Drivers Overview

The DRV8332DKDR is a three-phase PWM motor driver manufactured by Texas Instruments, featuring an integrated power stage with six N-channel power MOSFETs. It supports a supply voltage range of 8V to 60V and delivers up to 5A continuous phase current with a 7A peak capability. The device utilizes a 36-pin DPowerPak package (DRV8332DKD variant) or tape-and-reel configuration for surface mount assembly. Key electrical characteristics include low on-resistance MOSFETs for high efficiency and independent half-bridge supplies for precise current sensing.
