GSR809 - Reset IC

Description

The GSR809 are microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +3.3V, +3.0V, or 2.5V, 1.8V powered circuits.

GSR809 Reset IC Product Description The GSR809 are microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +3.3V, +3.0V, or 2.5V, 1.8V powered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 200ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The GSR809 have push-pull outputs and have an active-low /RESET output.
