TPS3808G50-Q1
Description
The TPS3808Gxx-Q1 microprocessor supervisory circuits monitor system voltages from 0.4 V to 5 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 useradjustable delay time after the SENSE voltage and MR return above their thresholds.
