CAT812JTBI-GT3

Supervisors Overview

The CAT812JTBI-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 fixed overvoltage threshold of 4 V. The device provides a push-pull output with a reset delay time of 20 µs. It is housed in an SOT-143-4 surface-mount package and supports industrial temperature ranges from -40°C to +85°C. The component draws a typical operating current of 6 µA and dissipates up to 320 mW. It lacks manual reset, watchdog timer, or battery backup switching capabilities.

Supervisors Feature Summary

• Provides active high supervision with push-pull output capability
• Features low quiescent current consumption for power efficiency
• Includes fast reset delay response time
• Operates across extended industrial temperature ranges

Supervisors Applications

• Portable equipment power management
• Battery-powered systems
• Consumer electronics
• Industrial control systems

Supervisors Procurement Notes

Verify the specific suffix GT3 confirms tape and reel packaging requirements. Confirm RoHS compliance status through official documentation as details may vary. Check current lifecycle status as the part is listed as obsolete in some channels. Ensure the SOT-143-4 footprint matches your PCB design constraints before ordering.

Supervisors Selection Notes

Select this component when a fixed 4 V overvoltage threshold is required for single-channel monitoring. The push-pull output allows direct interfacing with various logic families without additional pull-up resistors. Consider the 20 µs delay for applications requiring rapid fault detection. Evaluate the 6 µA standby current against system power budget constraints.

Supervisors Part Context

This part belongs to the CAT812 series of voltage supervisors from onsemi. It is specifically engineered for compact designs due to its small SOT-143-4 package. The series focuses on providing reliable power monitoring for portable and battery-operated devices where space and power efficiency are critical design parameters.

Supervisors Replacement Considerations

Check for CAT812LTBI-GT3 as a potential variant within the same family. Verify pinout compatibility and electrical specifications before substituting. Consult official cross-reference guides for confirmed equivalents.
