CAT811JTBI-GT3

Supervisors Overview

The CAT811JTBI-GT3 is a microprocessor power supply supervisor from onsemi, designed to monitor a single voltage rail. It features an active-low push-pull reset output and includes a manual reset input for system control. The device operates within an industrial temperature range of -40°C to +85°C and offers low power consumption with a typical supply current of 6µA. It provides reset validity down to VCC = 1.0V and ensures power supply transient immunity. The component is housed in a compact SOT-143 package.

Supervisors Feature Summary

• Manual reset input capability
• Active-low reset output configuration
• Power supply transient immunity

Supervisors Applications

• Computers and servers
• Laptops
• Embedded control systems
• Wireless communications equipment

Supervisors Procurement Notes

Verify the specific threshold voltage suffix (e.g., JTBI) against the design requirement, as the CAT811 family offers multiple fixed voltage options. Confirm package availability and lead times through authorized distributors. Ensure the manual reset pin is properly utilized if required by the system architecture. Check for end-of-life status or obsolescence notices prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel supervision with active-low output is required. The manual reset feature allows external override of the reset signal. Consider the operating voltage range and temperature specifications to ensure compatibility with the target application environment. Compare against direct replacements like the MAX811 if legacy compatibility is necessary.

Supervisors Part Context

This part belongs to the CAT811/CAT812 series of supervisory circuits. The CAT811 variant specifically provides an active-low reset, distinguishing it from the CAT812 which offers active-high output. These devices are engineered as direct replacements for Maxim Integrated's MAX811/MAX812 families, ensuring pin-to-pin compatibility and functional equivalence in industrial applications.

Supervisors Replacement Considerations

Direct replacement for MAX811 in industrial temperature range applications.
