MAX706RESA-TP from TECH PUBLIC, in a SOP-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	MR	input	Manual-Reset Input (active-low). Triggers a reset pulse when pulled below 0.8V. Has internal ~250µA pull-up current (max 600µA). Can be driven by TTL/CMOS logic or shorted to GND via a pushbutton switch.
2	VCC	power_in	Supply input. Operating range 1.0V to 5.5V (TA=0°C to +70°C); absolute maximum -0.3V to +6.0V. Typical supply current 80µA (max 150µA).
3	GND	power_in	Ground reference for all signals.
4	PFI	input	Power-Fail Voltage Monitor Input. When PFI is less than the 1.25V threshold, PFO goes low. High input impedance (input current ±25nA max). Connect to GND or VCC when unused.
5	PFO	output	Power-Fail Output (active-low). Goes low and sinks current (3.2mA at 0.4V) when PFI is below 1.25V; otherwise remains high (VOH ≥ 0.7·VCC at 800µA source).
6	WDI	input	Watchdog Input. If WDI stays high or low for the 1.6s (typ) timeout, the internal watchdog expires and WDO goes low. Floating or three-stating WDI disables the watchdog. Timer clears on reset assertion, WDI three-state, or a WDI edge. VIL=0.8V, VIH=3.5V at VCC=5V.
7	RESET	output	Active-Low Reset Output. Pulses low for 200ms (typ) when triggered and stays low while VCC is below the reset threshold (2.63V for R version). Remains low for 200ms after VCC rises above threshold or MR goes from Low to High. VOL ≤ 0.3V at 1.2mA sink.
8	WDO	output	Active-Low Watchdog Output. Pulls low when the internal 1.6s watchdog timer expires and remains low until the watchdog is cleared. Also goes low during low-line conditions (VCC below reset threshold). Unlike RESET, WDO has no minimum pulse width. VOL ≤ 0.4V at 1.2mA sink; VOH ≥ 0.7·VCC at 800µA source.
