CAT809LTBI-GT3 Description

Short technical summary and product information.

The ON Semiconductor CAT809LTBI-GT3 is a supervisory circuit that monitors power supplies in digital systems. It generates a reset signal that is asserted when the power supply voltage drops below a preset threshold and remains asserted for at least 140 ms after the voltage has risen above the threshold.

 

This device features a nominal voltage threshold of 4.63V and an active low, push-pull reset output. It is designed to ignore fast power supply transients and guarantees correct output state down to 1.0V VCC. The operating temperature range is -40°C to +85°C.

 

The CAT809LTBI-GT3 is available in a compact SOT-23-3 package, suitable for surface mount applications. It is a direct replacement for MAX809 devices in applications operating over the industrial temperature range.

 

Applications include computers, servers, laptops, wireless communications, embedded control systems, and intelligent instruments.
