SM5200

HICHON · Battery Management · SOT-23-6

SM5200 from HICHON, in a SOT-23-6. 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 CHRG output Open-drain charge-status indicator. Pulled low (strong pull-down) while charging (constant-current, constant-voltage, or trickle); high-impedance otherwise. With a 10 uF cap on BAT and no battery installed, this pin pulses at ~0.5-4 s to indicate 'no battery'. Drive typ. VOL ≤ 0.3 V at 5 mA sink.
2 GND power_in Device ground reference for all internal circuitry and the return for the internal power FET.
3 BAT power_out Charge-current output to the single-cell Li-ion battery. Regulated float voltage 4.2 V ±1%. Programmable charge current up to 500 mA; supplies ~-2.5 uA into the battery in standby (self-discharge is essentially eliminated). Absolute max -4.2 V to 7 V; continuous short to GND allowed.
4 VCC power_in Positive input supply from USB or adapter. Operating range 4.0 V-6.5 V (typ. 5 V); UVLO threshold ~3.6 V with ~200 mV hysteresis. Absolute max -0.3 V to 9 V. Bypass with ≥1 uF ceramic to GND.
5 STDBY output Open-drain end-of-charge / standby indicator. Pulled low (strong pull-down) when the charge cycle has terminated (battery full); high-impedance during any active charge phase or when VCC is absent. Typ. VOL ≤ 0.3 V at 5 mA sink.
6 PROG bidirectional Charge-current program, charge-current monitor, and shutdown pin. Program charge current with a 1% resistor to GND: RPROG = 1000 / IBAT (Ω, with IBAT in A) - pin regulates to 1.0 V and sources IBAT/1000 through RPROG. Also serves as a real-time charge-current monitor. Pulling this pin above ~1.2 V (manual shutdown threshold) or leaving RPROG open puts the device in shutdown (ICC ≈ 40 uA). Max pin current 800 uA; abs. max -0.3 V to VCC+0.3 V.

CAD (KiCad official)

  • Symbol: SM5200
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: sm5200-etched.step / sm5200-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm5200.step / sm5200.glb are the bare package body.

Provenance

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

  • Datasheet: HICHON datasheet (None pp, sha256 58dc3dc609303add, 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
