APX825A-31W6G-7 from Diodes Incorporated, in a SOT-26. 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) when VCC is below the -31 threshold (~3.08V typ), during power-up, and while MR is held low. Remains low for td (~200ms typ) after the reset condition clears. VOL <= 0.4V.
2	GND	power_in	Device ground reference.
3	RESET	output	Active-high reset output (complement of pin 1). Driven high while a reset condition is present and for td (~200ms typ) after the condition clears. VOH >= 0.8*VCC.
4	MR	input	Active-low manual reset input. Driving MR low forces RESET active. Internally pulled up to VCC through ~60kOhm, so it can be left open or driven by a pushbutton to GND. tW(MR) >= 100ns.
5	WDI	input	Watchdog input. Must see a rising or falling edge within the ttout window (1.6s typ, 1.12s min) or RESET is asserted for td. Leave floating/unconnected to disable the watchdog. tW(WDI) >= 50ns; IIH/IIL ~120uA.
6	VCC	power_in	Supply voltage input, 1.1V to 5.5V recommended (6.0V abs max). Monitored against the internal -31 threshold (~3.08V typ). Bypass with a 100nF ceramic capacitor close to the pin. ICC ~30uA typ.
