**MICRONE** · Battery Management · SOP-8

ME4058C6SG 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 | COMP | passive | Compensation, soft-start and shutdown pin: charging starts when COMP reaches 850 mV, pulling COMP below 600 mV turns the charger off, and it needs a 2.2 µF (or larger) capacitor in series with a 0.5 kΩ resistor, with an internal 150 µA source into the capacitor. |
| 2 | VCC | power_in | Input supply pin: place a 0.1 µF (or larger) capacitor on VCC and a low-ESR 10 µF input capacitor close to the P-channel MOSFET; the 8.4 V/8.7 V versions operate from 8.9 V to 20 V with absolute maximum 20 V. |
| 3 | GATE | output | Gate drive output for an external P-channel MOSFET, clamped to no more than 8 V below VCC so that MOSFETs with gate-source turn-on voltage of 8 V or less can be used. |
| 4 | GND | power_in | IC ground; a large copper area around the GND pin is recommended because it dissipates significant heat, and a 2.2 µF capacitor should be connected between VCC and GND as close to the pins as possible. |
| 5 | CHRG | output | Charge-status output that is pulled low by an internal NMOS to drive an LED while charging, goes high impedance when charge is finished by timer or the charger is shut down, and has a weak 25 µA pull-down at end of charge; absolute maximum rating is -0.3 V to 8 V. |
| 6 | BAT | input | Battery voltage sense input that requires a 22 µF bypass capacitor to minimize ripple; when VBAT is within 250 mV of VCC the device enters sleep mode and reduces ICC to 9 µA, with absolute maximum rating of -0.3 V to 14 V. |
| 7 | SENSE | input | Current-amplifier sense input connected to BAT through the sense resistor RSENSE, where charge current equals 110 mV / RSENSE; absolute maximum rating is -0.3 V to 14 V. |
| 8 | NTC | input | Negative-temperature-coefficient thermistor input: connect a 10 kΩ NTC to GND, and charging is suspended when the pack temperature is outside the window set by the hot (355 mV typ.) and cold (2.4 V typ.) thresholds, resuming automatically when it returns; absolute maximum rating is -0.3 V to 8 V. |
