GSR803 - Reset IC

General Description

The GSR803 is microprocessor (μP) supervisory circuit used to monitor the power supplies in μP and digital systems.

It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or 2.5V powered circuits.

Key Features

  • Precision monitoring of Supply Voltages.
  • Available Threshold Options: - 4.63V (GSR803L) - 4.38V (GSR803M) - 4.00V (GSR803J) - 3.08V (GSR803T) - 2.93V (GSR803S) - 2.63V (GSR803R) - 2.32V (GSR803Z).
  • 140ms Minimum Reset Pulse Width.
  • Open-Drain Output.
  • 10μA Supply Current Typically.
  • Power Supply Transient Immunity.
  • RoHS Compliant.

GSR803 Reset IC Product Description The GSR803 is microprocessor (μP) supervisory circuit used to monitor the power supplies in μP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or 2.5V powered circuits. The circuit perform a single function: it asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The GSR803 has an open-drain output stage and has an active-low output which requires a pullup resistor that can be connected to VCC or other supply.
