ME4064AM5G

MICRONE · Battery Management ICs · SOT-23-5

ME4064AM5G 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 is pulled low by an internal switch while the battery is charging and is high impedance otherwise.
2 GND power_in Ground.
3 BAT power_out Battery connection pin for the positive battery terminal that supplies charge current and regulates 4.2V, with BAT current below 2μA in disable or sleep mode.
4 VCC power_in Positive input supply voltage (4.0V to 8.0V) that powers the internal circuit; when VCC falls within 80mV of the BAT voltage the part enters low-power sleep mode with IBAT below 2μA.
5 PROG passive Charge current setting and monitor pin where a resistor RPROG to GND programs the current, with the pin regulated to 0.1V in precharge and 1V in constant-current mode (IBAT = VPROG/RPROG × 1100).
