MIC2039BYM6-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 | VIN | power_in | Power switch and logic supply input, specified for 2.5 V to 5.5 V operation with absolute maximum of -0.3 V to +6 V to GND. |
| 2 | GND | power_in | Input and output return (ground) pin for the device. |
| 3 | EN | input | Logic-compatible enable control that turns the switch on/off; logic-low is at most 0.5 V and logic-high at least 1.5 V, it must not be left floating, and it should not exceed VIN by more than 500 mV. |
| 4 | FAULT/ | output | Active-low open-drain fault status flag that goes low on an overcurrent lasting longer than tFAULT/ or on thermal shutdown, requires an external pull-up (10 kΩ recommended) to an external supply, and is rated up to 5.5 V with a maximum sink current of 25 mA. |
| 5 | ILIMIT | passive | Current-limit set pin; connect a resistor from this pin to GND to program the limit from 0.2 A to 2.5 A (for example 287 Ω gives 1.0 A), and do not leave it floating. |
| 6 | VOUT | power_out | Power switch output, rated from -0.3 V to VIN. |
