Product Overview

The TPS3808G01DBVT 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 ≤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.
  • 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

Applications

Signal Processing; Computers & Computer Peripherals; Portable Devices; Power Management
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.
