DRV8323RSRGZR

DRV8323RSRGZR is a Texas Instruments three-phase intelligent gate driver in a 48-pin VQFN (RGZ) package on a 2500-unit large reel — 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 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 SPI interface is the selection point: this S variant exposes gate-drive strength, protection thresholds and detailed fault registers to firmware, so drive behaviour can be tuned and diagnosed in software across production units. Business impact: register-level fault readback shortens failure analysis on returned drives, and one hardware design can serve several motor ratings by configuration alone. Selection advice: choose the S code when the controller budget includes SPI firmware; the hardware-pin sibling DRV8323RHRGZR in the same RGZ-48 package avoids firmware but freezes settings at layout. Match the full DRV8323RSRGZR code — the H/S letter is the interface, not a grade. Parameters verified against the TI DRV8323R datasheet and product page.
