ADM811LARTZ-REEL7

Analog Devices · Supervisor And Reset ICs · SOT-143

ADM811LARTZ-REEL7 from Analog Devices, in a SOT-143. 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 GND power_in Ground reference for all signals, 0 V.
2 RESET output Active-low logic output that stays low while VCC is below the reset threshold or MR is low, and for at least 140 ms after VCC rises above the reset threshold (at least 300 ms for the ADM811-3T); it remains valid (low) down to VCC of 1 V.
3 MR input Active-low manual reset input that ignores input pulses of 100 ns or less (typical) and is guaranteed to accept pulses greater than 10 µs; leave floating when not used.
4 VCC power_in Monitored supply voltage of 2.5 V, 3 V, 3.3 V, or 5 V; a 0.1 µF decoupling capacitor between VCC and GND is recommended.
