The microprocessor supervisory circuits monitor system voltages asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The RESET output remains low for the user adjustable delay time after the SENSE voltage and MR return above their thresholds. Datasheet is available in Texas Instruments website.
