MIC2019A-1YM6-TR

Microchip Tech · Power Distribution Switches · SOT-23-6

MIC2019A-1YM6-TR from Microchip Tech, in a SOT-23-6. 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 ENABLE input Switch enable input; the datasheet gives VIL(MAX) 0.5 V and VIH(MIN) 1.5 V, with input current up to 5 µA for 0 V ≤ VEN ≤ 5 V.
2 GND power_in Ground reference for the switch and its control circuitry.
3 VIN power_in Supply input that powers both the output switch and the internal control circuitry, specified for a 2.5 V to 5.5 V operating range.
4 ILIMIT input Sets the current limit threshold through a resistor connected from ILIMIT to GND, adjustable from 0.1 A to 0.9 A for the MIC2019A/MIC2009A family.
5 VOUT power_out Switch output that drives the load; the power FET is bidirectional when enabled and can conduct from VOUT to VIN when VOUT exceeds VIN.
6 FAULT/ output Open-drain fault status output that goes low during current limiting or thermal shutdown, with VFAULT of at most 0.4 V at IOL = 10 mA.
