TPS3808G09DBVR Datasheet PDF - TI

DESCRIPTION

●The TPS3808xxx family of microprocessor supervisory circuits monitor system voltages from 0.4V to 5.0V, 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 their thresholds.

●FEATURES

●• Power-On Reset Generator with Adjustable

●   Delay Time: 1.25ms to 10s
