Shenzhen Fuman · Battery Management · SOT-23-6
TC4058H6 from Shenzhen Fuman, in a SOT-23-6. 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 | External LED pin that indicates charging status: it is pulled low while charging, and it is high-impedance when charging is complete or under protection. |
| 2 | GND | power_in | Chip ground reference for the charger IC. |
| 3 | BAT | power_out | Battery positive connection that serves as the charge output to the cell; the absolute input voltage rating to ground is -0.3 to 11 V. |
| 4 | VIN | power_in | Chip supply and charge input, with a recommended input voltage of 4.5 to 5.5 V and an absolute maximum of -0.3 to 40 V to ground. |
| 5 | DONE | output | External LED pin that by default indicates charge-full status, or optionally indicates the VIN voltage status. |
| 6 | ISET | passive | Charge current setting pin; a high-precision resistor RSET from ISET to GND sets the constant charge current, with RSET specified between 10K and 100K, and the chip does not charge if ISET is left floating. |
