ADM811RARTZ-REEL7

Analog Devices · Monitors & Reset Circuits · SOT-143

ADM811RARTZ-REEL7 from Analog Devices, in a SOT-143. 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 GND power_in Ground reference for all signals, 0 V.
2 /RESET output Active-low logic output (ADM811 variant). RESET remains low while VCC is below the reset threshold or when /MR is low; RESET then remains low for at least 140 ms after VCC rises above the reset threshold. VOL <= 0.3 V @ ISINK = 1.2 mA; VOH >= 0.8*VCC @ ISOURCE = 500 uA.
3 /MR input Manual Reset. Active-low debounced input; ignores input pulses of 100 ns or less (typical) and is guaranteed to accept input pulses greater than 10 us. Internally pulled up (10-30 kOhm typ 20 kOhm). Leave floating when not used.
4 VCC power_in Monitored supply voltage (2.5 V, 3 V, 3.3 V, or 5 V options; 2.63 V typical reset threshold for the R variant). A 0.1 uF decoupling capacitor between VCC and GND is recommended. Absolute maximum VCC = -0.3 V to +6 V.
