MICRONE · AC-DC Controllers And Regulators · SOP-8
ME4312BSG 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 | RED | output | Charge-status red LED pin that sinks current; red is on during normal constant-current charging and turns off when charge current falls to 12% of the limit current. |
| 2 | VOUT | output | Output pin that can only sink current, with an output voltage of 400 mV at a 10 mA pull-down current. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | VCTRL | input | Voltage-control loop input, referenced to the internal 1.21 V (±1%) voltage reference. |
| 5 | VCC | power_in | Supply pin; the datasheet recommends 2.5 V to 36 V, with an absolute maximum of 36 V. |
| 6 | VSENSE | input | Current-control loop input, referenced to the internal 74 mV low-voltage reference (70 to 78 mV at Iout = 2.5 mA). |
| 7 | ICTRL | input | Current-detection and light-transition adjustment pin; with ICTRL at -70 mV the pin outputs 18 µA. |
| 8 | GREEN | output | Charge-status green LED pin that sinks current; green turns on and red turns off when charge current drops to 12% of the limit current. |
