APX823-29W5G-7 from Diodes Incorporated, in a SOT-25-5. 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	RESET	output	Active-low reset output. Asserted low while VCC is below the negative-going threshold VTH- (typ. 2.93 V for the -29 option) and held low for the delay time td (typ. 200 ms) after VCC recovers. Also driven low by MR assertion or a WDI watchdog time-out. VOL = 0.4 V max at IOL = 1 mA; VOH = 0.8xVCC min at IOH = -20 uA.
2	GND	power_in	Device ground return. 0 V reference for VCC and all logic thresholds.
3	MR	input	Active-low manual reset input. Driving MR low forces RESET active; on release, RESET remains low for delay time td (typ. 200 ms). Internally pulled up to VCC through ~60 kOhm, so the pin may be left open when unused. Minimum active pulse width tW = 100 ns; VIL <= 0.3xVCC, VIH >= 0.7xVCC.
4	WDI	input	Watchdog input. A rising or falling transition on WDI within the watchdog time-out interval tWD (typ. 1.6 s, min 1.12 s, max 2.4 s) retriggers the watchdog timer. If no transition occurs within tWD, RESET is driven low for td. Leaving WDI unconnected (high-Z) disables the watchdog. Minimum pulse width 50 ns; VIL <= 0.3xVCC, VIH >= 0.7xVCC.
5	VCC	power_in	Supply voltage input, 1.1 V to 5.5 V recommended operating range (6.0 V absolute max). Monitored against the internal negative-going threshold VTH- (typ. 2.93 V for the -29 option, hysteresis ~50 mV). Bypass with a 0.1 uF ceramic capacitor near the pin. Typical supply current ICC = 30 uA at VCC = VTH-+0.2 V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`apx823-29w5g-7.step`	85 KB	You want the bare part, or you mark your own boards.
`apx823-29w5g-7-etched.step`	2.5 MB	You want the part with `APX823-29W5G-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 604 faces against 102 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.
