MIC2548-1YMM

Microchip Tech · Power Management Specialized - PMIC · MSOP-8

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.
