LM3710YQMM-232 from Texas Instruments, in a VSSOP-10-0.5mm. 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	VCC	power_in	Power supply input; the LM3710 operating range is 1.0 V to 5.5 V and supply current is 28 µA typical (50 µA max) with all inputs at VCC and outputs floating.
2	MR	input	Manual-reset input with an internal 56 kΩ pull-up; reset is asserted when MR is pulled below VMRT for more than 25 µs and remains active until MR rises above VMRT and the reset timeout period expires.
3	PFI	input	Power-fail comparator input compared to a 1.225 V internal reference (1.200 V to 1.250 V); PFO goes low when PFI is below VPFT, with input current limited to ±75 nA.
4	WDI	input	Watchdog input that monitors for transitions; if no transition occurs within the watchdog timeout period tWD, reset is asserted, and WDI is a high-impedance input.
5	GND	power_in	Ground reference for all signals.
6	NC	unconnected	No connect; test input used at the factory only, so leave floating.
7	LLO	output	Low-line output that goes low when VCC falls below VLLOT (1.01 to 1.03 times VRST, falling), usable as an early power-fail warning or NMI source.
8	PFO	output	Power-fail logic output that goes low when PFI is below VPFT and otherwise remains high.
9	NC	unconnected	No connect; test input used at the factory only, so leave floating.
10	RESET	output	Active-low reset output (LM3710) that pulses low for tRP (reset timeout period) and stays low while VCC is below the reset threshold or MR is below VMRT, and is ensured valid for VCC above 1 V.
