ME4084BSPG from MICRONE, in a SOP-8-EP. 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 | TEMP | input | Battery temperature sense input: charging stops when TEMP is below 45% or above 80% of VCC, and tying TEMP to GND disables the temperature function. |
| 2 | PROG | passive | Constant-current charge setting and charge-current monitor: a resistor to GND sets the charge current (RPROG = 910/IBAT per the datasheet), and VPROG is 1.0 V typical in current mode at RPROG = 1.52 kΩ. |
| 3 | GND | power_in | Ground reference for the charger; the datasheet recommends wide copper on this pin for heat dissipation. |
| 4 | VCC | power_in | Input supply pin for the internal circuits, operating range 4.7 V to 6.5 V (typ 5.0 V), absolute maximum -0.3 to 24 V, with the charger entering sleep mode when VCC is within 70 mV of BAT. |
| 5 | BAT | power_out | Battery connection pin where the charger delivers charge current; the regulated float voltage is 4.2 V for ME4084BSPG (4.158 V to 4.242 V over 0 °C to 85 °C), with absolute maximum BAT voltage of 16 V. |
| 6 | STDBY | output | Open-drain charge-complete status output that is pulled low when charge termination is detected and is high-impedance otherwise; absolute maximum voltage 24 V. |
| 7 | CHRG | output | Open-drain charge-status output that is pulled low while charging and is high-impedance otherwise; absolute maximum voltage 24 V. |
| 8 | CE | input | Chip enable: a logic high (2.0 V minimum) starts normal charging operation and a logic low (0.8 V maximum) stops the chip; absolute maximum voltage 24 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
