DRV5021A2QDBZR

Texas Instruments · Hall Switches · SOT-23

DRV5021A2QDBZR from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in 2.5 V to 5.5 V power supply pin. Bypass to GND with a 0.1 µF (minimum) ceramic capacitor rated for VCC. Absolute maximum 6.0 V.
2 OUT output Hall-sensor open-drain output. Pulls low when magnetic flux density exceeds BOP and goes high-impedance when it falls below BRP. Requires an external pull-up resistor; sinks up to 20 mA (30 mA absolute max), RDS(on) ~8 Ω at 5 mA / 3.3 V.
3 GND power_in Device ground reference pin.

CAD (KiCad official)

  • Symbol: DRV5021A2QDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: drv5021a2qdbzr-etched.step / drv5021a2qdbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); drv5021a2qdbzr.step / drv5021a2qdbzr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (None pp, sha256 fa61625ff5ebcd2b, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
