ME4052ASPG 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 | CS | input | Charge-current programming / current-sense input. An external resistor (R_CS) between VIN and CS sets the constant-charge current (V_SNSC ≈ 195 mV typ across R_CS in CC mode; V_SNST ≈ 19 mV typ in trickle mode; V_TEMI ≈ 30 mV typ triggers termination). |
| 2 | CHRG | output | Open-drain charge status indicator. Sinks current to light an LED to VCC while charging; goes high-Z (LED off) when charging completes. V_OL ≈ 0.3 V at I_CHRG = 5 mA. |
| 3 | STDBY | output | Open-drain standby / charge-complete status indicator. Drives an external LED to VCC to indicate charging is finished (standby). V_OL ≈ 0.3 V at I_STDBY = 5 mA. |
| 4 | BAT | power_out | Battery output / voltage sense pin. Delivers charge current to the 2-cell Li-ion pack and senses pack voltage for the 8.4 V float regulation loop. Rated for 1000 mA and up to 18 V absolute max. |
| 5 | GND | power_in | Ground reference for the IC. |
| 6 | VIN | power_in | Chip supply input from adapter/USB. Operating range 8.9-15 V (typical 9 V), 18 V absolute max. UVLO ≈ 3.6 V, OVP ≈ 15 V. |
| 7 | TEMP | input | Battery temperature sense input. Connects to an NTC thermistor to monitor pack temperature; charging is suspended when V_TEMP is outside 45%-80% of V_IN (V_TEMP-L ≈ 45 %V_IN rising release, V_TEMP-H ≈ 80 %V_IN). Tie directly to GND if the temperature-monitor feature is unused. |
| 8 | EN | input | Chip enable. Tie high (V_ENON ≥ 2 V) to enable the charger; tie low (V_ENOFF ≤ 0.4 V, to GND) to shut down the chip (I_IN ≈ 20 µA in shutdown). |
| 9 | BAT_PAD | power_out | Exposed thermal pad on the underside of the ESOP-8. Must be connected to BAT (pin 4) per the datasheet - it is electrically the BAT node and also serves as the primary thermal dissipation path (θ_JA = 63 °C/W). |
