DRV8323RHRGZR

DRV8323RHRGZR is a Texas Instruments three-phase intelligent gate driver in a 48-pin VQFN (RGZ) package — for BLDC and PMSM drives with external MOSFETs: 6 V to 60 V supply, Smart Gate Drive with 10 mA to 1 A source and 20 mA to 2 A sink current, an integrated buck regulator delivering 600 mA across a 0.8 V to 60 V output range, three low-side current-sense amplifiers with 5/10/20/40 V/V bidirectional or unidirectional gain, 3.3 V 30 mA LDO, 1.8 V/3.3 V/5 V logic and 12 µA sleep current, over -40°C to +125°C. The hardware interface is the selection point: this H variant is pin-configured, so protection thresholds and gate strength are fixed at layout with no SPI firmware to maintain. Business impact: Smart Gate Drive lets one layout serve several MOSFET choices by trimming drive current instead of re-spinning the board. Selection advice: the RGZR code is the 2500-unit large-reel ordering code and is orderable in its own right — the RGZT code is the same device in a 250-unit small reel, a packing difference only. If production needs register-level fault detail and software-tunable thresholds, choose the SPI sibling DRV8323RSRGZR instead. Parameters verified against the TI DRV8323R datasheet and package option addendum.
