ME4074AM5G

MICRONE · Battery Management · SOT-23-5

ME4074AM5G from MICRONE, 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 output. Pulls low during charging; goes high-impedance when charging is complete or terminated. Connect through a series 1k-10k current-limiting resistor to an LED for status indication, or tie directly to GND if unused.
2 GND power_in Device ground reference.
3 BAT power_out Charge current output to the single-cell Li-ion battery. Regulated to VFLOAT = 4.2V in constant-voltage mode. In CC mode, IBAT = 1000 / RPROG. Absolute max pin current 800 mA; absolute max voltage -0.3 to 6.5 V.
4 VCC power_in Input supply voltage (typically from a USB port or AC adapter). Operating range 4.0 V to 6.5 V (typ 5.0 V). Undervoltage lockout threshold ~3.7 V.
5 PROG input Charge current programming pin. Connect a resistor RPROG from PROG to GND to set the constant-current charge level: IBAT = 1000 V / RPROG. In CC mode VPROG = 1 V. Floating this pin places the device in shutdown mode.
