ADM706SARZ

Analog Devices · Supervisor And Reset ICs · SOIC-8

ADM706SARZ from Analog Devices, in a SOIC-8. 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 MR input Manual reset input: taking it below 0.6 V generates a RESET/RESET, it is internally debounced, and an internal 70 μA pull-up holds it high when floating.
2 VCC power_in Power supply input with an operating range of 1.0 V to 5.5 V; a 0.1 µF decoupling capacitor should be placed between VCC and GND.
3 GND power_in Ground reference for all signals at 0 V.
4 PFI input Noninverting input to the power-fail comparator, which drives PFO low when PFI falls below 1.25 V; if unused, PFI connects to GND.
5 PFO output Power-fail comparator output that goes low when PFI is less than 1.25 V.
6 WDI input Watchdog input: if WDI stays either high or low longer than the watchdog timeout period (1.00 s min, 1.60 s typ, 2.25 s max), WDO goes low, and any high-to-low or low-to-high transition clears the timer.
7 RESET output Active-low reset output that goes low for 200 ms when VCC is below the reset threshold (2.93 V typ for the ADM706S) or MR is pulled low, and remains low for 200 ms after VCC recovers or MR returns high.
8 WDO output Watchdog output that goes low when the watchdog timer times out from WDI inactivity, stays low until the timer is cleared, and also goes low whenever VCC is below the reset threshold.
