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 undervoltage threshold options for monitoring 1.8 V, 2.5 V, 3.3 V, and 5 V supplies. There is also an adjustable input option with an undervoltage threshold voltage of 0.6 V.The ADM13305-18, ADM13305-25, and ADM13305-33 models have two internally fixed thresholds. The ADM13305-4 and ADM13305-5 offer one internally fixed threshold and one externally programmable threshold via a resistor string. See the Ordering Guide for a list of all available options.During power-up, RESETis 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 either of the SENSEv inputs remains 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 voltage monitored by the SENSEv pins falls below its associated falling threshold, VIT−, RESET the output asserts. The ADM13305 features both an active high RESET and an active low RESET output.As well as providing power-on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within the preset timeout period. A reset signal can also be asserted by an external push button through the manual reset input pin.The ADM13305 is available in an 8-lead, narrow body SOIC package. The device operates over the extended industrial temperature range of −40°C to +85°C.
