The ADM13305 is a dual voltage supervisor designed to monitor two supplies and provide a reset signal to DSP and microprocessor-based systems. There are five models available, all of which feature a combination of internally pretrimmed under-voltage and over-voltage thresholds.
The ADM13305 is a dual processor supervisor that monitors two supply rails and provides power‑on reset and watchdog functions for DSPs and microcontrollers. It is available in several threshold options (1.8 V, 2.5 V, 3.3 V, 5 V) and an adjustable 0.6 V option, all in an 8‑lead narrow‑body SOIC package.
Key features include a supply voltage range of 2.7 V to 5.5 V, a typical watchdog timeout of 1.6 s, a minimum reset timeout of 140 ms, and operation over –40 °C to +85 °C. The device provides both active‑high and active‑low reset outputs, a manual reset input, and low supply current (40 pA).
