CAX810ZTBI-T3

Supervisors Overview

The CAX810ZTBI-T3 is a single-channel voltage supervisory integrated circuit manufactured by onsemi. 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 monitors one input with a typical threshold of 4.06 V for overvoltage detection and 3.93 V for undervoltage detection. It includes a fixed reset delay time of 240 ms and consumes a typical operating current of 8 µA. The component is housed in a SOT-23-3 package and supports surface mount installation.

Supervisors Feature Summary

• Provides continuous monitoring of a single power rail with defined overvoltage and undervoltage thresholds.
• Delivers a digital signal via an active high, push-pull output stage for direct interface with logic circuits.
• Incorporates a fixed internal reset delay timer to ensure stable system recovery after voltage transients.

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated equipment needing efficient power management
• Embedded systems utilizing microcontrollers or processors

Supervisors Procurement Notes

Verify the specific suffix T3 indicates tape and reel packaging configuration. Confirm the device status as discontinued or end-of-life through official onsemi channels before finalizing design-in decisions. Ensure compatibility with existing PCB footprints for SOT-23-3 packages during procurement planning.

Supervisors Selection Notes

Select this component when a single-channel supervisor with active high output is required. Consider the 8 µA quiescent current for battery-sensitive designs. Verify that the 240 ms reset delay aligns with system startup timing requirements. Ensure the 5.5 V maximum rating exceeds the monitored rail voltage.

Supervisors Part Context

This part belongs to the CAX810 series of supervisory circuits from onsemi. It is designed for general-purpose power management applications where reliable voltage monitoring is critical. The series offers various threshold options and package configurations to suit different system constraints.

Supervisors Replacement Considerations

Check for CAT810JTBI-GT3 as a potential alternative within the same family. Verify pinout compatibility and electrical parameter alignment before substitution. Consult official documentation for cross-reference validity.
