RY2231B1D4

RYCHIP · Battery Management · DFN-4-EP(1x1)

RY2231B1D4 from RYCHIP, in a DFN-4-EP(1x1). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Power supply pin; the absolute maximum VDD input voltage is -0.3 V to 6 V.
2 GND power_in Grounding end, connected to the battery core negative pole; the datasheet gives no separate electrical limit for this pin.
3 NC unconnected Not connected; the datasheet states no function for this pin.
4 VM input Charger minus voltage input pin; the absolute maximum VM input voltage is -6 V to 10 V.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
