TC4058H5

Shenzhen Fuman · Battery Management · SOT-23-5

TC4058H5 from Shenzhen Fuman, 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 CHRG output Open-drain charge-status indicator. Pulled low (LED on) while charging; high impedance when charge is complete or in protection state. Drives an external LED to GND through a series resistor (typ. 2 kΩ).
2 GND power_in Chip ground reference for all internal analog and digital circuitry.
3 BAT power_out Battery positive terminal and charge current output. Absolute maximum 11 V; connect a 10 μF ceramic capacitor to GND close to the pin. Sources up to ~1 A during constant-current charging.
4 VIN power_in Main power input and charge source. Recommended operating range 4.5-5.5 V (absolute maximum 40 V; OVP threshold ~6.5 V). Decouple with a ceramic capacitor to GND; capacitor voltage rating must exceed 25 % of the maximum applied VIN.
5 ISET input Charge-current programming pin. Connect a resistor R_SET (10 kΩ-100 kΩ) from ISET to GND to set the constant-current level per I_BAT_CC = 0.9 / R_SET × 10000 (A), up to ~1 A. Leaving ISET floating disables charging.

CAD (KiCad official)

  • Symbol: TC4058H5
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tc4058h5-etched.step / tc4058h5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tc4058h5.step / tc4058h5.glb are the bare package body.

Provenance

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

  • Datasheet: Shenzhen Fuman datasheet (13 pp, sha256 0d6620362571cb3d, 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.
