CAT823ZSDI-GT3

Supervisors Overview

The CAT823ZSDI-GT3 is a system supervisory voltage reset circuit manufactured by onsemi. It monitors a single input voltage and provides a reset signal when the supply deviates from specified thresholds. The device features an active high and active low push-pull output, a manual reset pin, and a watchdog timer function. It operates within a supply voltage range of 1.2 V to 5.5 V with a typical quiescent current of 4 µA. The component is housed in a TSOT-23-5 package and supports industrial operating temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage supervision, watchdog timer, and manual reset functionality into a single compact package.
• Provides configurable active high and active low push-pull outputs for flexible logic interfacing.
• Designed for low power consumption with ultra-low quiescent current suitable for battery-operated systems.

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Industrial control systems needing reliable voltage monitoring
• Automotive electronics demanding robust supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix 'Z' against the official datasheet to confirm threshold voltage and package variations. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check for end-of-life notices or obsolescence warnings prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both watchdog and manual reset capabilities is required. Ensure the monitored voltage falls within the 1.2 V to 5.5 V operational range. Verify that the TSOT-23-5 package dimensions fit the available PCB space constraints.

Supervisors Part Context

This part belongs to the CAT823 series of supervisory circuits designed for system reliability. It complements other power management solutions by providing essential fault detection and recovery mechanisms for microprocessors and memory devices in complex electronic architectures.

Supervisors Replacement Considerations

Consult the official cross-reference list for verified substitutes. Ensure any replacement maintains identical pinout, voltage thresholds, and package compatibility to avoid redesign efforts.

Supervisors FAQ

What is the function of the manual reset pin?

The manual reset pin allows users to force the output into the reset state independently of the voltage monitoring conditions.

Does the CAT823ZSDI-GT3 include a watchdog timer?

Yes, the device integrates a watchdog timer to detect software failures or abnormal system behavior.
