DS1830 Reset Sequence Pushbutton
01/29/2023
Product Details
The DS1830 Reset Sequencer monitors the power supply for an in-tolerance condition and the pushbutton reset input for a manual reset. First a precision temperature-compensated reference and comparator circuit monitors the status of the power supply and when an out-of-tolerance condition is detected, an internal power fail signal is generated that forces the reset lines to go to an active state. If the power supply returns to an in-tolerance condition, reset 1 will release followed by reset 2 and finally reset 3. Sequencing of resets allows for systems to power-up in an orderly manner providing superior reliability.
