Product Overview

The TPS3808G01DBVR is a low quiescent current programmable-delay Supervisory Circuit 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 ≤3.3V. The reset delay time can be set to 20ms by disconnecting the CT pin, 300ms by connecting the CT pin to VDD using a resistor or can be user-adjusted between 1.25ms and 10s by connecting the CT pin to an external capacitor. The TPS3808 device has a very low typical quiescent current of 2.4µA, so it is well-suited to battery-powered applications.
  • Manual reset (MR) input
  • Open-drain reset output
  • Fixed threshold voltages for standard voltage
  • Rails from 0.9 to 5V and adjustable voltage
  • Power-on reset generator with adjustable delay time of 1.25ms to 10s
  • 2.4µA Typical very low quiescent current
  • 0.5% Typical high threshold accuracy
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
