CAT823ZTDI-GT3

Supervisors Overview

The CAT823ZTDI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single-input power rails. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 2.32 V with an overvoltage threshold of 2.38 V. The device includes a manual reset input and a watchdog timer function. It provides active high and active low push-pull outputs with a reset delay time of 200 ms. Operating at a quiescent current of 4 uA, it is housed in a TSOT-23-5 package and functions reliably between -40°C and +85°C.

Supervisors Feature Summary

• Integrates manual reset capability alongside watchdog timer functionality for comprehensive system protection.
• Delivers dual output polarity options through active high and active low push-pull configurations.
• Maintains ultra-low power consumption suitable for battery-operated applications.

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable power supervision
• Industrial control units operating in varying temperature environments

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details via official documentation. Ensure compatibility with existing board layouts given the TSOT-23-5 footprint. Review datasheet specifications for electrical characteristics before integration. Validate supplier credentials to mitigate counterfeit risks.

Supervisors Selection Notes

Select this component when precise voltage monitoring near 2.32 V is required. Consider the integrated watchdog feature if software reliability is critical. Evaluate the low quiescent current against system power budgets. Assess the need for both active high and low outputs for interface flexibility. Verify thermal performance within the specified operating temperature range.
