MSKSEMI · Battery Management · SOT-23-6
TP4057-MS from MSKSEMI, 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 | Open-drain charge-status output that an internal switch pulls low while the charger is charging (VCHRG max 0.6V at 5mA) and otherwise leaves high impedance; absolute maximum rating is -0.3V to 9V. |
| 2 | GND | power_in | Ground pin, listed in the pin table only as 地 (ground) with no further function stated. |
| 3 | BAT | power_out | Charge-current output to the battery; the internal precision resistor divider sets the final float voltage to 4.2V and is disconnected in shutdown; absolute range is -4.2V to 7V and BAT pin current is rated at 600mA. |
| 4 | VCC | power_in | Positive input supply that must be bypassed with at least one 1µF capacitor; the datasheet states VCC varies from 4V to 6.5V, and the charger enters shutdown when VCC falls to within 80mV of the BAT voltage; absolute maximum rating is 0V to 9V. |
| 5 | STDBY | output | Open-drain charge-complete indicator that an internal switch pulls low when charging is complete and otherwise leaves high impedance (VSTDBY max 0.6V at 5mA); absolute maximum rating is -0.3V to 9V. |
| 6 | PROG | passive | Charge-current set, monitor and shutdown pin: a 1% resistor to GND sets the current and holds PROG at 1V in constant-current mode, and a voltage above 2.6V shuts the charger down; absolute range is -0.3V to VCC+0.3V with a maximum pin current of 800µA. |
