MIC2026-1YM-TR from Microchip, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	ENA	input	Switch A enable input. Logic-compatible; active-high on the MIC2026-1 (this variant). VEN threshold typ 1.7 V rising, 1.45 V falling; 250 mV hysteresis. Input current ±1 µA over 0 V to 5.5 V.
2	FLGA	output	Fault Flag A output. Active-low, open-drain; pulled low to indicate overcurrent or thermal shutdown on channel A. Overcurrent must persist longer than tD (typ 3 ms) before FLGA asserts. Max IFLG 25 mA; ON resistance typ 10 Ω at IL=10 mA, VIN=5 V.
3	FLGB	output	Fault Flag B output. Active-low, open-drain; pulled low to indicate overcurrent or thermal shutdown on channel B. Overcurrent must persist longer than tD (typ 3 ms) before FLGB asserts. Max IFLG 25 mA.
4	ENB	input	Switch B enable input. Logic-compatible; active-high on the MIC2026-1 (this variant). Same electrical characteristics as ENA.
5	OUTB	power_out	Switch B output. High-side switched supply for channel B, sourced from IN through a 140 mΩ (typ 90 mΩ) MOSFET. Delivers 500 mA continuous; internally current-limited (typ 0.9 A) with soft-start.
6	GND	power_in	Ground return for the device.
7	IN	power_in	Switch and logic supply input. 2.7 V to 5.5 V operating range (abs max 6 V). Feeds both channel switches; a 0.1 µF decoupling capacitor is recommended. UVLO releases at 2.4 V (typ) rising, 2.15 V (typ) falling.
8	OUTA	power_out	Switch A output. High-side switched supply for channel A, sourced from IN through a 140 mΩ (typ 90 mΩ) MOSFET. Delivers 500 mA continuous; internally current-limited (typ 0.9 A) with soft-start.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mic2026-1ym-tr.step`	122 KB	You want the bare part, or you mark your own boards.
`mic2026-1ym-tr-etched.step`	2.3 MB	You want the part with `MIC2026-1YM-TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 591 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
