CAT1162WI30

Supervisors Overview

The CAT1162WI-30-G is a supervisory circuit manufactured by onsemi, designed for CPU systems with integrated 16K EEPROM. It operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 3 V. The device provides a reset delay time of 270 ms and supports manual reset functionality. It lacks a watchdog timer and battery backup switch. The component utilizes an SOIC-8 package for surface mount installation and offers active high, active low, and open drain output types. It monitors one input channel and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates 16K serial CMOS EEPROM with hardware write protection for microcontroller-based systems
• Provides precision voltage supervision with brown-out protection capabilities
• Supports multiple reset output configurations including active high, active low, and open drain
• Features manual reset functionality without integrated watchdog timer

Supervisors Applications

• CPU system monitoring in embedded applications
• Microcontroller power supply supervision
• Systems requiring integrated memory and reset control
• Brown-out protection circuits

Supervisors Procurement Notes

Verify the exact suffix (e.g., -G, -T3) as the base model number may refer to multiple packaging variants. Confirm RoHS compliance status and lead times through official distributors, as availability varies by region. Ensure the selected variant matches the required package type and operating temperature range for the specific application environment.

Supervisors Selection Notes

Select this component when a combined solution for voltage supervision and non-volatile memory storage is required. Choose based on the specific threshold voltage needed for the target power rail. Consider the absence of a watchdog timer if system hang protection is necessary, opting for alternative models like the CAT1161 series in such cases. Verify package compatibility during PCB layout design.

Supervisors Part Context

This part belongs to the CAT1162 series of supervisory circuits from onsemi. These devices integrate I2C serial CMOS EEPROM with precision reset controllers. The series is designed to provide complete memory and supervisory solutions for microcontroller-based systems, combining power management and data storage in a single low-power CMOS package.

Supervisors Replacement Considerations

CAT1162LI-30-G is a documented pin-compatible alternative offering the same functional specifications in a DIP package. Verify package dimensions and mounting requirements before substitution. Other family members like CAT1161 include additional watchdog features not present in this model.
