CAT809MTBI-GT3 Description

Short technical summary and product information.

The CAT809MTBI-GT3 from ON Semiconductor is a 3-pin microprocessor power supply supervisor designed to monitor voltage levels 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 140ms after the voltage has risen above the threshold.

 

This device features an active low, push-pull reset output and is designed for precision monitoring of power supplies. It is guaranteed to be in the correct state at VCC levels as low as 1.0V, offering immunity to power supply transients. The operating temperature range is -40°C to +85°C, making it suitable for industrial applications.

 

The CAT809MTBI-GT3 is available in a compact SOT-23-3 surface mount package, suitable for space-constrained designs. It is a direct replacement for MAX809 devices in applications operating over the industrial temperature range.

 

Key electrical characteristics include a nominal operating voltage of 4.38V and a reset timeout of 140ms minimum. The device monitors a single voltage rail.
