ADM8690ARNZ

Analog Devices · Monitors & Reset Circuits · SOIC-8

ADM8690ARNZ 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 VOUT power_out Output voltage; VCC or VBATT is internally switched to VOUT depending on which is at the highest potential, supplies up to 100 mA to CMOS RAM, and should be connected to VCC if VOUT and VBATT are not used.
2 VCC power_in Power supply input, 5 V nominal; VCC or VBATT is internally switched to VOUT depending on which is at the highest potential.
3 GND power_in Ground, the 0 V reference for all signals.
4 PFI input Power-fail input, the noninverting input to the power-fail comparator; PFO goes low when PFI is less than 1.3 V, and PFI should be connected to GND or VOUT when not used.
5 PFO output Power-fail output of the comparator that goes low when PFI is less than 1.3 V, and the comparator is turned off with PFO low when VCC is below VBATT.
6 WDI input Three-level watchdog input; if it stays high or low longer than the watchdog timeout period RESET pulses low, the timer resets on each transition, and the watchdog is disabled if WDI is floating or driven to midsupply.
7 RESET output Active-low logic output that goes low if VCC falls below the reset threshold (typically 4.65 V) or the watchdog is not serviced, stays low for 50 ms after VCC returns above the threshold, and has an internal 3 μA pull-up.
8 VBATT power_in Backup battery input; VBATT or VCC is internally switched to VOUT depending on which is at the highest potential.
