This document introduces Analog Devices' ADM6711/ADM6713 product, which is a microprocessor supervisory circuit suitable for use in microprocessor-based systems. The circuit has the characteristics of precise monitoring of 2.5 V, 3 V, 3.3 V and 5 V power supply voltages, low power consumption (12 μA), reset timeout period of 140 ms (minimum), manual reset input, output stages push-pull RESET output (ADM6711) and open-drain RESET output (ADM6713).
The ADM6711 and ADM6713 are low‑power reset generator circuits designed for microprocessor‑based systems. They monitor supply voltages, provide a reset signal on power‑up, power‑down and brown‑out, and include a debounced manual reset input.
The devices are offered in a 4‑lead SC70 package, feature push‑pull (ADM6711) or open‑drain (ADM6713) reset outputs, and provide immunity to fast supply glitches. Detailed specifications, pin descriptions and typical application circuits are included.
| Supply Voltage Range | 1.0 V to 5.5 V |
|---|---|
| Supply Current | 16 pA to 60 pA |
| Reset Voltage Threshold (ADM671_L) | Typical 4.63 V |
| Reset Active Time (typical) | 140 ms |
| Reset Output Low Voltage | 0.3 V |
| Glitch Immunity | 100 ns |
The reset timeout period is typically 140 ms.
ADM6711 provides a push‑pull reset output, while ADM6713 provides an open‑drain reset output.
The devices are immune to supply glitches as short as 100 ns.
