# ME4074CM5G

**MICRONE** · Battery Management · SOT-23-5

ME4074CM5G from MICRONE, in a SOT-23-5. 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 pulls strongly low while charging and is high-impedance when charge is complete or the charger is off; when used for an LED it must be in series with a 1 kΩ to 10 kΩ current-limiting resistor, and it can be tied to GND if the indication is not needed. |
| 2 | GND | power_in | Ground pin for the charger. |
| 3 | BAT | power_out | Charge current output to the battery; in constant-current mode IBAT = 1000/RPROG, with a BAT pin absolute maximum of -0.3 V to 6.5 V and a BAT pin current rating of 800 mA. |
| 4 | VCC | power_in | Power input pin for the charger, specified at 4.0 V to 6.5 V with 5 V typical, and absolute maximum of -0.3 V to 6.5 V. |
| 5 | PROG | passive | Charge current programming pin where a resistor to GND sets the charge current, with VPROG = 1 V in constant-current mode, and the absolute maximum range is -0.3 V to Vcc+0.3 V. |
