ADM13307-5 Triple Processor Supervisor

RS Components Part # 759-0392

Manufactured by Analog Devices- Part # ADM13307-5ARZ - SO8 SMD Package

DESCRIPTION

The ADM13307 is a triple voltage supervisor designed to monitor up to three voltage levels in DSP and microprocessor-based systems.
There are five models available, all of which feature a combina-tion of internally pretrimmed undervoltage threshold options for monitoring 1.8 V, 2.5 V, 3.3 V, and 5 V supplies. There are also two adjustable input options with undervoltage thresholds of either 0.6 V or 1.25 V.
The ADM13307-5 offers one internally fixed threshold and two externally programmable thresholds.
During power-up, ¬RESET is asserted when the supply voltage exceeds 1.1 V. The device then monitors the SENSEv input pins and holds the ¬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. Subsequently, if a volt-age monitored by the SENSEv pins falls below its associated falling input threshold voltage, VIT−, the RESET output asserts.
