CN825Z from ShangHai Consonance Elec, 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	/MR	input	Manual reset input, active-low. Pulling this pin low triggers a reset pulse on both RESET outputs. Internally pulled up to VCC via 50 kΩ (38-62 kΩ), so it may be left floating when unused. Can be driven by CMOS, open-drain, or open-collector; a contact switch to GND is sufficient (no external debounce needed). /MR pulse width min 1 µs; /MR-to-reset delay max 500 ns.
2	GND	power_in	Ground / negative supply return.
3	/RESET	output	Active-low reset output. Driven low whenever VCC is below the reset threshold (2.32V typ. for CN825Z), /MR is low, or the watchdog timer overflows. Once the fault clears, /RESET remains low for at least 140 ms (200 ms typ.) before releasing high. VOL=0.3V max at ISINK=3.2 mA; guaranteed valid down to VCC=1.1V (VOL=0.3V max at ISINK=150 µA).
4	VCC	power_in	Positive supply input; also the monitored voltage. Operating range 1.1V to 6.5V (abs-max 6.5V). Continuously compared against the internal 2.32V reset threshold (CN825Z, ±1%). Supply current 2.7 µA typ. below threshold, 16 µA typ. above threshold.
5	RESET	output	Active-high reset output. Driven high whenever VCC is below the reset threshold, /MR is low, or the watchdog timer overflows. Once the fault clears, RESET stays high for at least 140 ms (200 ms typ.) before returning low. VOH=VCC-1V min at ISOURCE=1 mA; guaranteed valid down to VCC=1.1V (VOH=1.0V at ISOURCE=8 µA).
6	WDI	input	Watchdog input. Must toggle (high-to-low or low-to-high) within the watchdog timeout (0.95 s min, 1.6 s typ., 2.25 s max) or the watchdog overflows and asserts reset on both outputs. Minimum WDI pulse width 50 ns; input leakage ±50 nA; thresholds 0.25VCC (low) / 0.75VCC (high). Watchdog is held cleared while VCC is below threshold or /MR is low.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cn825z.step`	97 KB	You want the bare part, or you mark your own boards.
`cn825z-etched.step`	1.4 MB	You want the part with `CN825Z` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 350 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.
