CAT809MSDI-GT3

Supervisors Overview

The CAT809MSDI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed to monitor power supplies in digital systems. It features an active low push-pull reset output and operates within a supply voltage range of 1.2 V to 5.5 V. The device provides a threshold voltage of 4.63 V with an overvoltage threshold of 4.70 V. It includes a fixed reset delay time of 240 ms and consumes a typical operating supply current of 8 uA. The component is housed in an SC-70-3 package and supports an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring for standard power supply voltages including +5.0 V, +3.3 V, +3.0 V, and +2.5 V systems.
• Features a push-pull active low reset output configuration for direct drive capability.
• Ensures reset validity down to a minimum VCC of 1.0 V with immunity to power supply transients.

Supervisors Applications

• Computers and servers
• Wireless communications equipment
• Embedded control systems

Supervisors Procurement Notes

Verify the specific threshold voltage and package variant against the official datasheet before procurement, as suffixes indicate distinct electrical parameters. Confirm end-of-life status and availability constraints directly with authorized distributors or onsemi sales representatives. Ensure RoHS compliance requirements are met for the target application environment.

Supervisors Selection Notes

Select this component when a push-pull active low reset signal is required for single-input voltage supervision. It serves as a direct replacement for MAX809 devices in industrial temperature applications. Consider the 240 ms reset delay and 8 uA quiescent current for timing and power budget calculations.

Supervisors Part Context

This part belongs to the CAT809 series of microprocessor power supply supervisors from onsemi. The series offers precision monitoring for various logic system voltages. The CAT809 variant specifically utilizes a push-pull output architecture, distinguishing it from open-drain or active-high alternatives within the same family.
