GENERAL DESCRIPTION
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, 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 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-, the RESET 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 -40C to +85C.

ADM13305 THEORY OF OPERATION
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 of 0.6 V. The ADM13305-18, ADM13305-25, and ADM13305-33 have two internally fixed thresholds, while 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.

INPUT CONFIGURATION
The ADM13305 is powered through VDD. To increase noise immunity in noisy applications, place a 0.1 F capacitor between the VDD input and ground. The SENSEv inputs are resistant to short power supply glitches. Do not allow an unused SENSEv input to float or to be grounded, instead connect it to a supply voltage greater than its specified threshold voltage. Typically, the threshold voltage at each adjustable SENSEv input is 0.6 V. To monitor a voltage greater than 0.6 V, connect a resistor divider network to the device as depicted in Figure 13, where,
Once the supplies monitored at the SENSEv pins rise above their associated threshold level, the RESET signal remains low for the reset timeout period before deasserting. Subsequently, if either of the supplies monitored by the SENSEv pins falls below its associated threshold the RESET output reasserts. The ADM13305 features both an active-low, push-pull RESET output and an active-high, push-pull RESET output.
WATCHDOG TIMER
The ADM13305 features a watchdog timer that monitors microprocessor activity. A timer circuit is cleared with every low-to-high or high-to-low logic transition on the watchdog input pin (WDI). If the timer counts through the preset watchdog timeout period of 1.6 sec, RESET is asserted, as shown in Figure 15. The microprocessor is required to toggle the WDI pin to avoid being reset. Therefore, failure of the microprocessor to toggle WDI within the timeout period indicates a code execution error and the reset pulse generated restarts the microprocessor in a known state. The watchdog timer can be disabled by leaving WDI floating.

RESET OUTPUT
The reset outputs are guaranteed to be in the correct state for VDD down to 1.1 V. During power-up, RESET is asserted when the supply voltage becomes greater than 1.1 V.

MANUAL RESET (MR)
The ADM13305 features a manual reset input, which when driven low, asserts the reset output, as shown in Figure 16. When MR transitions from low to high, reset remains asserted for the duration of the reset active timeout period before deasserting. An external push-button switch can be connected between MR and ground to allow the user to generate a reset.
