Microchip Tech · Power Distribution Switches · SOIC-16

MIC2027-2YM from Microchip Tech, in a SOIC-16. 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 FLG output Fault Flag A is an active-low open-drain output that goes low on overcurrent or thermal shutdown, and an overcurrent must last longer than tD (typically 3ms) before the flag asserts.
2 ENA input Switch A logic-compatible enable input, active low on the -2 variant (MIC2027-2), with a 0.8V low threshold and 2.4V high threshold.
3 OUTA power_out Switch A output, the source of the channel A high-side MOSFET, which supplies the load with RDS(on) of 150mΩ maximum at VIN = 5V.
4 GND power_in Ground reference for the device.
5 IN(C/D) power_in Channel C and D switch and logic supply input, operating over 2.7V to 5.5V with an absolute maximum of +6V.
6 OUTC power_out Switch C output, the source of the channel C high-side MOSFET.
7 ENC input Switch C logic-compatible enable input, active low on the -2 variant.
8 FLGC output Fault Flag C is an open-drain output that asserts on overcurrent (after tD) or thermal shutdown.
9 FLGD output Fault Flag D is an open-drain output that asserts on overcurrent (after tD) or thermal shutdown.
10 END input Switch D logic-compatible enable input, active low on the -2 variant.
11 OUTD power_out Switch D output, the source of the channel D high-side MOSFET.
12 GND power_in Ground reference for the device.
13 IN(A/B) power_in Channel A and B switch and logic supply input, operating over 2.7V to 5.5V with an absolute maximum of +6V.
14 OUTB power_out Switch B output, the source of the channel B high-side MOSFET.
15 ENB input Switch B logic-compatible enable input, active low on the -2 variant.
16 FLGB output Fault Flag B is an open-drain output that asserts on overcurrent (after tD) or thermal shutdown.
