ADM8614Y263ACBZ-R7

Analog Devices · Supervisor And Reset ICs · WLCSP-6(1x1.5)

ADM8614Y263ACBZ-R7 from Analog Devices, in a WLCSP-6(1x1.5). 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
A1	VCC	power_in	Power supply input and the voltage monitored by the ADM8614, operating from 0.9 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended as close to the device as possible between VCC and GND.
A2	GND	power_in	Ground reference for the device.
B1	WDI	input	Watchdog timer input that must toggle to prevent a watchdog reset, with input high threshold 0.9 V minimum and low threshold 0.4 V maximum, and pulses as short as 85 ns detected.
B2	WD_DIS	input	Watchdog function disable input that disables the watchdog when tied high and should be connected to ground if unused, with VIH of 0.9 V minimum and VIL of 0.4 V maximum.
C1	WDT_SEL	input	Watchdog timeout selection input that extends the watchdog timeout to 100 sec when pulled high and returns it to the base value when pulled low, and toggling it resets the watchdog timer.
C2	RESET	output	Active low, open-drain RESET output that asserts within 23 µs to 26 µs (typical) when the monitored voltage falls below threshold and is guaranteed valid once VCC exceeds 0.9 V.

CAD (KiCad official)

Symbol: ADM8614Y263ACBZ-R7
Footprint: Package_CSP:WLCSP-6_1.4x1.0mm_P0.4mm
3D model: WLCSP-6(1x1.5), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.35 mm nominal DSBGA height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
3D model files: adm8614y263acbz-r7-etched.step / adm8614y263acbz-r7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adm8614y263acbz-r7.step / adm8614y263acbz-r7.glb are the bare package body.
