CAT823RTDI-GT3

Supervisors Overview

The CAT823RTDI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed to monitor system power rails and generate reset signals. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.63 V. The device provides both active high and active low outputs in a push-pull configuration, ensuring compatibility with various logic families. It includes manual reset functionality for system control. Packaged in a TSOT-23-5 surface-mount format, it supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides dual output polarity options (active high and active low) with push-pull drive capability
• Includes manual reset input for direct system control and initialization
• Monitors single voltage rail with a fixed trip point for reliable supervision

Supervisors Applications

• Processor supervisor circuits requiring stable power-up sequencing
• Embedded systems needing manual reset capability alongside automatic monitoring
• Industrial control boards operating in extended temperature environments

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm package integrity and pin alignment against the TSOT-23-5 specification before integration. Review latest datasheet revisions for any parameter updates or handling instructions specific to this batch.

Supervisors Selection Notes

Select this component when dual-output flexibility and manual reset are required in a compact footprint. Ensure the 2.63 V threshold aligns with the monitored rail's minimum operating voltage. Consider the push-pull output strength for driving downstream logic without external pull-ups.

Supervisors Part Context

Part of the CAT823 series of voltage supervisors, offering enhanced functionality over basic monitors by including manual reset inputs. Designed for applications requiring precise power management and system stability in space-constrained designs.

Supervisors Replacement Considerations

Check for CAT823 variants with different thresholds or packages. Verify electrical compatibility with existing circuitry before substitution.
