CAT810JTBI-GT3

Supervisors Overview

The CAT810JTBI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring power supplies in digital systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features an active high, push-pull reset output. The device monitors a single input with a threshold voltage of 4 V, specifically detecting under-voltage at 3.93 V and over-voltage at 4.06 V. It includes a fixed reset delay time of 240 ms and consumes only 8 uA of operating current. Packaged in a compact SOT-23-3 surface-mount format, it functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides precise monitoring of power supply voltages using floating gate technology for stable threshold accuracy.
• Features an active high, push-pull reset output that eliminates the need for external pull-up resistors.
• Ensures correct output state during fast transients and low voltage levels down to 1.0 V.

Supervisors Applications

• Monitoring +5.0 V power supply systems
• Digital system power supervision
• Microprocessor power supply support

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Check current lifecycle status as obsolescence may affect long-term availability. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Supervisors Selection Notes

Select this component when an active high reset signal is required for systems powered by +5.0 V rails. The push-pull output simplifies interface design compared to open-drain alternatives. Consider the 240 ms reset delay for timing-sensitive applications. Verify that the SOT-23-3 package fits the board space constraints and thermal management needs of the target design.

Supervisors Part Context

This part belongs to the CAT810 series of 3-pin microprocessor power supply supervisors. It serves as a direct replacement for legacy MAX810 devices in industrial temperature applications. The series utilizes Analog EEPROM technology to offer various industry-standard threshold levels for different voltage systems.

Supervisors Replacement Considerations

The CAT810JTBI-GT3 is a direct pin-for-pin replacement for the Maxim MAX810 in industrial temperature range applications. Designers transitioning from older generations should verify that the active high output polarity matches their system logic requirements.
