ME4069ASPG

MICRONE · Battery Management · ESOP-8

ME4069ASPG from MICRONE, in a ESOP-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 EN input Enable pin that switches the chip on and off; pulling EN low to GND shuts the chip down and terminates charging.
2 BAT input Negative feedback pin that receives the battery voltage feedback through an external output resistor; hot-plug applications require an additional electrolytic capacitor of more than 47 µF on BAT.
3 SEN input Charge current setting pin, where the output current is set by the external sense resistor as IOUT = 100 mV / R5.
4 SW output Switch output of the PWM buck converter, driving the external inductor (L1 4.7 µH in the typical application).
5 GND power_in IC ground; the datasheet lists pin 5 together with the Thermal PAD as the GND connection.
6 VIN power_in Power input with an operating range of 4.7 V to 5.5 V and a 6.0 V withstand rating; the chip shuts off when VIN exceeds the 6 V overvoltage threshold, requires a 10 µF input capacitor, and hot-plug applications need an additional electrolytic capacitor of more than 47 µF.
7 CHRG output Charge status output that is low during trickle and constant-current charging and goes high-impedance when charging is complete, in temperature-fault or sleep mode, or when input is removed; it can drive an LED.
8 TEMP input Battery temperature sense input that normally has a 20 kΩ resistor to GND; charging is suspended when TEMP falls below 540 mV at high temperature or rises above 2.3 V at low temperature.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
