TPL5010DDCT from Texas Instruments, in a SOT-23-6. 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	VDD	power_in	Supply voltage input. Recommended operating range 1.8 V to 5.5 V; absolute maximum 6.0 V. Typical supply current is 35 nA at 2.5 V in operation mode.
2	GND	power_in	Device ground reference.
3	DELAY/M_RST	input	Dual-function pin: (1) Time-interval selection - a resistor REXT (500 Ω to 170 kΩ) between this pin and GND sets the WAKE interval, converted once after POR. (2) Manual reset - momentarily pulling this pin high to VDD (≥20 ms; VIH ≥ 1.5 V) triggers a manual reset (RSTn assertion). The reset switch is also connected to this pin.
4	DONE	input	Watchdog acknowledge input. Digital signal driven by the µC (low-to-high transition) to indicate successful processing of the WAKE signal. Must be asserted at least 20 ms before the next WAKE rising edge or the TPL5010 will assert RSTn. VIH = 0.7×VDD, VIL = 0.3×VDD.
5	WAKE	output	Timer output signal (push-pull). Digital pulsed output generated every tP period to wake the µC at the end of the programmed time interval. Pulse width typically 20 ms. Normally low. VOH ≥ VDD-0.3 at 100 µA, VOL ≤ 0.3 V at 100 µA.
6	RSTn	output	Reset output to the µC (open-drain, active low). Requires an external pull-up resistor (100 kΩ recommended to minimize current). Asserted low if DONE is not received in time, on manual reset, or during POR/REXT reading. Pulse width typically 320 ms. VOL ≤ 0.3 V at -1 mA.
