CAX810JTBI-T3

Supervisors Overview

The CAX810JTBI-T3 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 an active high push-pull output. The device detects over-voltage at a threshold of 4.06 V and under-voltage at 3.93 V, with a reset delay time of 140 ms minimum. It consumes 8 µA of operating current and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount format, it supports systems requiring precise power management without manual reset or watchdog capabilities.

Supervisors Feature Summary

• Provides active high push-pull output for reliable logic interfacing
• Monitors single input voltage rail with dedicated over and under-voltage detection
• Operates with low quiescent current consumption for energy efficiency
• Suitable for industrial environments with extended temperature rating

Supervisors Applications

• Industrial control system power monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for obsolescence notices or lifecycle changes as this part may be subject to discontinuation. Ensure packaging specifications match production line needs. Validate technical datasheet revisions against current design requirements.

Supervisors Selection Notes

Select this component when a single-channel supervisor with active high output is required. Consider the 140 ms reset delay and 8 µA current draw for power-sensitive designs. Verify that the SOT-23-3 package fits the PCB layout constraints. Ensure the monitored voltage stays within the 1.2 V to 5.5 V operational range. Compare against alternatives if manual reset or watchdog timer functionality is needed.

Supervisors Part Context

This part belongs to the CAT/CAX810 series of supervisory circuits from onsemi. It shares functional similarities with other members like CAT810JTBI-GT3 but differs in specific suffix designations which may indicate package or testing variations. The series is categorized under PMIC solutions for power management ICs, focusing on voltage monitoring applications.

Supervisors Replacement Considerations

CAT810JTBI-GT3 is a documented alternative within the same family. Verify pin compatibility and electrical parameter alignment before substitution. Check if the GT3 suffix indicates different packaging or environmental compliance compared to the T3 variant.
