RY2200At3

RYCHIP · Battery Management · SOT-23-3

RY2200At3 from RYCHIP, in a SOT-23-3. 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 VM input Charger minus (negative) voltage input pin. Senses the voltage between the battery negative terminal and the load/charger negative terminal for over-current, load short-circuit, and charger detection. Internally pulled to VDD through RVMD (~150 kΩ) in over-discharge state and to GND through RVMS (~10 kΩ) in over-current state. Absolute max: -6 V to +10 V.
2 GND power_in Ground / battery cell negative terminal reference. All internal voltage detection thresholds are referenced to this pin.
3 VDD power_in Power supply pin, connects to battery positive terminal through the sense resistor R1 (typ. 1 kΩ) and bypassed to GND via C1 (typ. 0.1 μF). Absolute max: -0.3 V to +6 V. Operating current 3.9 μA typ., power-down 2.2 μA typ.

  • RY2200At3

CAD (KiCad official)

  • Symbol: RY2200At3
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: ry2200at3-etched.step / ry2200at3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ry2200at3.step / ry2200at3.glb are the bare package body.

Provenance

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

  • Datasheet: RYCHIP datasheet (None pp, sha256 6dff420fe9fba0cd, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
