MIC2548-1YMM from Microchip Tech, in a MSOP-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 | EN | input | Logic-compatible enable input, active-high for -1 (high >1.7V typ, low <1.5V typ), must not be floated; on MIC2548 it also resets the thermal shutdown latch. |
| 2 | FLG | output | Active-low open-drain fault flag output indicating overcurrent or thermal shutdown, latched low on thermal shutdown for MIC2548. |
| 3 | GND | power_in | Ground. |
| 4 | NC | unconnected | Not internally connected. |
| 5 | ILIM | passive | Current-limit set pin; connect an external resistor RSET to ground with 154 Ω < RSET < 2.29 kΩ (ILIMIT = 230V/RSET). |
| 6 | OUT | power_out | Switch output (MOSFET source); pins 6 and 8 must be externally connected together. |
| 7 | IN | power_in | Supply input (2.7V to 5.5V), output MOSFET drain, also powers internal circuitry. |
| 8 | OUT | power_out | Switch output (MOSFET source); pins 6 and 8 must be externally connected together. |
