TPL5010DDCR from Texas Instruments, in a SOT-23-Thin-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. Operating range 1.8 V to 5.5 V, absolute max 6 V. Typical supply current 35 nA (50 nA max) in timer operation mode.
2	GND	power_in	Ground reference for the device.
3	DELAY/M_RST	input	Time interval set and Manual Reset input. An external resistor (REXT) between this pin and GND selects the timer interval (100 ms to 7200 s across 1650 selectable intervals). A manual reset switch may also be connected to this pin; logic-high threshold V_IH = 1.5 V.
4	DONE	input	Watchdog acknowledgement input. Driven by the host microcontroller with a digital pulse (min 100 ns) to indicate successful processing of the WAKE signal. Logic thresholds V_IH = 0.7 x VDD, V_IL = 0.3 x VDD.
5	WAKE	output	Timer output signal, generated every t_IP period as a ~20 ms active-high digital pulse to wake up the host microcontroller. Push-pull output: V_OH >= VDD - 0.3 V @ 100 uA, V_OL <= 0.3 V @ -100 uA.
6	RSTn	output	Reset output, open-drain, active-low. Asserts a ~320 ms low pulse to reset the host microcontroller if DONE is not received within the programmed interval, or when a manual reset is triggered via DELAY/M_RST. Requires an external pullup (e.g. 100 kohm).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tpl5010ddcr.step`	97 KB	You want the bare part, or you mark your own boards.
`tpl5010ddcr-etched.step`	2.0 MB	You want the part with `TPL5010DDCR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 490 faces against 117 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.
