ME4056ASPG-N

MICRONE · Battery Management · ESOP-8

ME4056ASPG-N from MICRONE, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TEMP input Battery temperature sense input. Connect to the wiper of an NTC divider referenced to VCC; charging stops if V(TEMP) drops below ~45% VCC or rises above ~80% VCC (over/under-temperature). Tie directly to GND to disable temperature monitoring.
2 PROG passive Charge-current program pin. A resistor R_PROG from this pin to GND sets the constant-current level per I_BAT = 1300 * V_PROG / R_PROG (V_PROG ≈ 1.0 V). Also used internally for charge-current monitoring and C/10 termination detection.
3 GND power_in Device ground / power return. The ESOP-8 exposed thermal pad should also connect to this net for heat dissipation.
4 VCC power_in Charger supply input (4.0-7.0 V, 5 V typical; keep ≤ 5.5 V for full 0.9 A charging). When VCC falls to within ~80 mV of BAT the internal pass FET shuts off and the device enters sleep mode with < 2 µA battery leakage.
5 BAT power_out Battery connection. Sources the charging current and regulates to V_FLOAT = 4.2 V (A suffix) or 4.34 V (D suffix) during constant-voltage phase. Bypass with a low-ESR capacitor to GND.
6 /STDBY output Charge-complete status indicator, open-drain, active-low. Internal N-MOS pulls low when charge termination is detected; high-impedance in all other states. Typically pulled up through an LED to VCC.
7 /CHRG output Charging status indicator, open-drain, active-low. Internal N-MOS pulls low while the battery is being charged; high-impedance otherwise. Typically pulled up through an LED to VCC.
8 CE input Chip-enable input, active-high, Schmitt-trigger. Drive high to enable normal charging; drive low to disable and place the device in low-current standby. Compatible with TTL/CMOS logic levels.
