JSM4054R

JSMSEMI · Battery Management · SOT-23-5L

JSM4054R from JSMSEMI, in a SOT-23-5L. 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 CHRG output Charge status indicator output; the datasheet gives an absolute maximum CHRG voltage of 7 V and does not state its drive or sink limits.
2 GND power_in Ground reference pin for the device.
3 BAT power_out Charge current output to the single-cell Li-ion battery; absolute maximum BAT voltage is 7 V, BAT current is 500 mA, and BAT may be shorted continuously.
4 VCC power_in Input supply pin, operating range 4.5 V to 5.5 V (5.0 V typical), absolute maximum 7 V, with undervoltage lockout at 3.4 V.
5 PROG passive Charge current programming pin: a resistor from PROG to GND sets the constant charge current (RPROG = 10 kΩ gives about 100 mA, 2 kΩ gives about 500 mA), with PROG held at about 1 V in constant-current mode, absolute maximum PROG voltage VCC+0.3 V and maximum PROG current 800 µA.

  • 3D model: SOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: jsm4054r-etched.step / jsm4054r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); jsm4054r.step / jsm4054r.glb are the bare package body.

Provenance

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

  • Datasheet: JSMSEMI datasheet (5 pp, sha256 ed70cb56d389428f, retrieved 2026-10-18, 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: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
