Vishay GS809C
The GS809C and 810C are system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. • The GS809C has an active-low reset output, while the GS810C has an active-high reset output.| Part No. | GS809C |

DESCRIPTION
● No external components are required.● When the processor power supply voltage drops below the reset threshold, the reset output is driven active, in less than 40µs (TD1). Reset is maintained active for a time period (TD2), after the Vcc rises above the threshold voltage.
● To prevent jitter, the reset threshold voltage has a built-in hysteresis of 0.4% of VTH. Both devices have push/pull output drives.
● The reset signal is guaranteed valid, down to Vcc = 1.0V. Fig. 1 – Typical Application Diagram VCC VCC GS809C Reset VCC Processor Reset Input GND
● Low supply current of 3µA makes these devices well suited for battery powered applications. They are designed to reject fast transients from causing false resets.
● Both devices are available in a space-saving SOT-23 package. GND
