SM5213 from HICHON, in a SOT-23-5. 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 | STAT | output | Open-drain charge status indicator. Pulled low (sinks up to ~5 mA, VOL ≤ 0.6 V) while charging (typically drives a red LED); high-impedance when charging is terminated or in UVLO/fault conditions. Toggles at a 1-4 s period when BAT has a 10 µF cap and no battery is connected. |
| 2 | GND | power_in | Device ground reference for all internal circuitry and the ISET programming resistor return. |
| 3 | BAT | power_out | Charge current output to the single-cell Li-ion battery. Regulates to 4.2 V ±1% float voltage; supplies up to 800 mA (RISET = 1.2 kΩ) constant current and enters trickle mode (~ITRIKL) below VTRIKL ≈ 2.93 V. Recharge threshold ≈ 4.05 V. Rated to 20 V. |
| 4 | VIN | power_in | Charger input supply pin (also referred to as VCC). Normal operating range 4.5 V-7 V (absolute max 20 V), with over-voltage protection threshold ≈ 7 V (6.5-7.4 V) and UVLO ≈ 3.35 V. Accepts USB or AC-adapter supply. |
| 5 | ISET | bidirectional | Constant-current programming and charge-current monitor. A resistor RISET from this pin to GND sets IBAT ≈ 1000 × VISET / RISET (e.g. RISET = 1.2 kΩ → ~800 mA; 2 kΩ → ~480 mA). Pin regulates to ~1.0 V in current mode; charger terminates when VISET falls below 100 mV (C/10). Absolute max 6 V; internal 1 µA pull-up. Leaving RISET disconnected places the part in shutdown. |
