Details
The DS1831 multisupply monitor and reset monitors up to four system voltages: 5V supply, 3.3V (or 3V) supply, and two additional user configurable voltage monitors. DS1831 power for internal operation comes from the higher voltage level of the 3.3V input or the 5V input. One of these inputs must be greater than 1V for device operation. Pushbutton (manual reset) functionality is provided for the 5V reset, the 3.3V reset or for all reset outputs by the master pushbutton.FEATURES■ 5V power-on reset■ 3.3V power-on reset■ Two referenced comparators with separate outputs for monitoring additional supplies■ Internal power is drawn from higher of either the IN5V input or the IN3.3V input■ Excellent for systems designed to operate with multiple power supplies■ Asserts resets during power transients■ Pushbutton reset input for system override■ Maintains reset for user configurable times of 10ms, 100ms, or 1s■ Watchdog timer for software monitoring (DS1831A)■ Precision temperature-compensated voltage reference and voltage sensor■ 16 pin DIP and 16 pin 150mil SO available■ Operating Temperature of -40°C to +85°C
