The ADM13305 is a dual processor supervisor designed to monitor two supplies and provide a reset signal to DSP and microprocessor-based systems. It features adjustable voltage reference, maximum supply current, and a watchdog timer.
The ADM13305 monitors two supply voltages and provides reset signals to DSP and microprocessor‑based systems. It includes dual supervisory circuits, pre‑trimmed threshold options (1.8 V, 2.5 V, 3.3 V, 5 V) and an adjustable 0.6 V reference, plus a watchdog timer that can reset the processor if it fails to toggle within a preset timeout.
The device is supplied in an 8‑lead narrow‑body SOIC package and operates over an industrial temperature range of –40 °C to +85 °C. It offers both active‑low and active‑high push‑pull reset outputs, a manual reset input, and a watchdog input that can be disabled by leaving it floating.
