# ME8107A

**MICRONE** · AC-DC Controllers & Regulators · DIP-8

ME8107A from MICRONE, in a DIP-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 | VDD | power_in | Supply pin with 5uA startup current and about 1.8mA operating current, UVLO below 8.2V max and OVP at about 27.5V. |
| 2 | NC | unconnected | No connection. |
| 3 | GND | power_in | Chip ground, to be routed separately from power ground on the PCB. |
| 4 | FB | input | Feedback input from the optocoupler: 0.75-1.0V is burst mode, 1.0-3.7V is normal operation, and above 3.7V (or below 0.75V) for 88ms shuts off GATE output. |
| 5 | SENSE | input | Primary switch current sense input with 220ns leading edge blanking and a typical 0.85V overcurrent threshold. |
| 6 | NC | unconnected | No connection. |
| 7 | DRAIN | passive | Drain of the internal 600V high-voltage power MOSFET, connected to the transformer primary, and tied internally with pin 8. |
| 8 | DRAIN | passive | Drain of the internal 600V high-voltage power MOSFET, connected to the transformer primary, and tied internally with pin 7. |
