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). |
