CAT810RTBI-T3

Supervisors Overview

The CAT810RTBI-T3 is a microprocessor supervisory circuit manufactured by onsemi, designed to monitor voltage levels in embedded systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a reset threshold voltage of 2.63 V with an overvoltage threshold of 2.66 V. The device provides a push-pull active-high output and includes a fixed reset delay time of 240 ms. Packaged in a compact SC-70-3 surface-mount format, it supports an operating temperature range from -40 °C to +85 °C and consumes a typical quiescent current of 8 µA.

Supervisors Feature Summary

• Provides reliable power supervision for microprocessors and digital logic circuits through precise voltage monitoring.
• Features a push-pull active-high output stage capable of driving downstream reset inputs directly.
• Ensures system stability during power transitions via a fixed internal reset delay timer.

Supervisors Applications

• Microprocessor power supply monitoring
• Digital logic circuit supervision
• Portable electronic devices requiring low standby current

Supervisors Procurement Notes

Verify the specific suffix RTBI against official onsemi documentation to confirm pinout compatibility and electrical characteristics. Ensure the SC-70-3 package dimensions align with your PCB footprint requirements. Cross-reference the 2.63 V threshold specification with your system's nominal voltage levels to guarantee correct reset activation timing under all operating conditions.

Supervisors Selection Notes

Select this component when a low-profile SC-70-3 package is required for space-constrained designs. It is suitable for applications needing an active-high reset signal without manual reset functionality. Consider the 8 µA quiescent current for battery-operated systems where minimizing standby power consumption is critical for extended operational life.

Supervisors Part Context

This part belongs to the CAT810 series of supervisory circuits from onsemi, which are engineered for robust performance in consumer and industrial electronics. The series utilizes advanced BCD technology to deliver high accuracy and reliability. These devices are commonly integrated into portable gadgets and computing modules where stable power management is essential for proper system initialization.

Supervisors Replacement Considerations

Check for CAT810RSDI-T3 as a potential alternative if SC-70-3 packaging is acceptable, noting its similar 2.63 V threshold. Verify that any substitute maintains the same active-high push-pull output configuration and reset delay characteristics to ensure functional equivalence in the existing design.
