ADM13307-5ARZ

ADM13307-5ARZ is a triple processor supervisor that is designed to monitor up to three voltage levels in DSP and microprocessor-based systems. It offers one internally fixed threshold and two externally programmable thresholds. During power-up, active-low RESET is asserted when the supply voltage exceeds 1.1V. The device then monitors the SENSEv input pins and holds the active-low RESET output low as long as the SENSEv pins remain below the rising threshold voltage, VIT+. Once the supplies monitored at the SENSEv inputs rise above their associated thresholds, the reset signal remains low for the reset timeout period before deasserting. The manual reset input can be used to initiate a reset by means of an external push button or logic signal. It features both an active high RESET and an active low RESET output. Typical applications are supervising DSPs/microcontrollers, industrial and portable equipment, wireless systems, and notebook/desktop computers.
