3 Description
The TPS3808xxx family of microprocessor supervisory circuits monitors system voltages from 0.4 V to 5.0 V, 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 manual reset (MR) return above the respective...
