The TPS3808G33DBVR is a Low Quiescent Current Programmable Delay Supervisory Circuit that monitors system voltages from 0.4 to 5V, 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 thresholds. The TPS3808 device uses a precision reference to achieve 0.5% threshold accuracy for VIT
● Power-on reset generator with adjustable delay time (1.25ms to 10s)
● Very low quiescent current (2.4µA typical)
● High threshold accuracy (0.5% typical)
● Fixed threshold voltages for standard voltage rails from 0.9 to 5V & adjustable voltage down to 0.4V
● Manual reset (MR) input
● Open-drain reset output
● Green product and no Sb/Br
●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
