CAT824SSDI-GT3

Supervisors Overview

The CAT824SSDI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed to monitor system power integrity. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 2.93 V with an overvoltage threshold of 3.05 V. The device provides active high and active low push-pull outputs and includes a manual reset input. It incorporates a watchdog timer and offers a fixed reset delay time of 200 ms. The component consumes 6 uA of operating current and is housed in a SC-70-5 package, suitable for surface mount installation across temperatures from -40 C to +85 C.

Supervisors Feature Summary

• Provides dual active high and active low push-pull outputs for flexible logic interfacing
• Integrates a watchdog timer with manual reset capability for enhanced system reliability
• Operates with low quiescent current consumption suitable for power-sensitive applications

Supervisors Applications

• Microprocessor (MPU) system supervision
• Portable equipment power monitoring
• Battery-operated device reset control

Supervisors Procurement Notes

Verify the specific suffix 'GT3' against the manufacturer's latest documentation to confirm tape-and-reel packaging specifications and RoHS compliance status. Confirm that the SC-70-5 package variant matches your PCB footprint requirements. Check for any end-of-life notices or obsolescence warnings directly from onsemi before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-supply supervisor with both under-voltage and over-voltage detection is required. The 2.93 V threshold suits systems operating near standard logic levels. Ensure the 200 ms reset delay aligns with your microcontroller startup timing requirements. Verify that the SC-70-5 package dimensions fit within your available board space constraints.
