ME4312CSG

MICRONE · Battery Management ICs · SOP-8

ME4312CSG from MICRONE, in a SOP-8. 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 RED output Charging indicator red LED pin, which is lit while charging current is normal and off once current drops to the transition point.
2 VOUT output Output pin that can only sink current, with VOL of 400 mV typical at a 10 mA pull-down current.
3 GND power_in Ground reference pin.
4 VCTRL input Voltage control loop input, where the ME4312C reference is 1.210 V (range 1.204 V to 1.216 V) and input bias current is 50 nA typical at Vctrl=1.5 V.
5 VCC power_in Supply pin, with recommended supply range 2.5 V to 36 V and an absolute maximum of 36 V.
6 VSENSE input Current control loop input, where the ME4312C reference is 212 mV (range 206 mV to 218 mV).
7 ICTRL input Current control and transition-point adjustment input, where external resistors set the lower voltage reference and the pin draws 18 µA typical with ICTRL at -70 mV.
8 GREEN output Charging indicator green LED pin, which is lit when charging current falls to the transition point set by the Ictrl network.
