CAT1162WI-30-GT3

Supervisors Overview

The CAT1162WI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a precision reset controller with a 16-kilobyte serial EEPROM. The device operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 3 V with an overvoltage threshold of 3.15 V. It provides a manual reset input and delivers a reset delay time of 270 ms. The component supports active high, active low, and open drain output configurations. It consumes 3 mA during operation and lacks watchdog timer or battery backup switch functionalities. The unit is housed in an SOIC-8 package and functions reliably across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a precision voltage supervisor with a 16-kilobyte serial EEPROM for combined monitoring and data storage.
• Offers flexible output configuration options including active high, active low, and open drain states.
• Includes a manual reset input capability for external control of the reset signal generation.

Supervisors Applications

• CPU power supply monitoring in embedded systems
• Voltage supervision for microprocessor-based controllers
• Data retention management via integrated EEPROM in portable devices

Supervisors Procurement Notes

Verify the specific suffix designation against official documentation, as availability may vary between tape-and-reel and tube packaging formats. Confirm RoHS compliance status through current manufacturer declarations. Ensure the selected variant matches the required operating temperature range and package type for your design. Cross-reference part numbers carefully to distinguish between similar supervisory circuits within the same family.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated non-volatile memory is required. Consider the 3 V threshold and 270 ms reset delay for timing-sensitive applications. Evaluate the 3 mA operating current against system power constraints. Verify that the absence of a watchdog timer aligns with the target application's safety requirements before finalizing the selection.
