... 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 combina- tion 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 ...

... 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 ...
