CAT1162WI-30-G

Supervisors Overview

The CAT1162WI-30-G is a voltage supervisory circuit manufactured by onsemi, designed for CPU systems with integrated 16K serial CMOS EEPROM. It operates within a supply voltage range of up 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 is housed in an SOIC-8 surface-mount package and includes active high, active low, and open drain output options. The component lacks a watchdog timer and battery backup switch, operating across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a system power supervisor with brown-out protection and 16K I2C serial CMOS EEPROM with hardware write protection.
• Provides flexible reset output configurations including active high, active low, and open drain options.
• Supports manual reset input for system control without requiring a dedicated watchdog timer.

Supervisors Applications

• Microcontroller-based systems requiring combined memory and supervision
• CPU monitoring applications with brown-out protection needs
• Embedded designs utilizing I2C serial EEPROM for data storage

Supervisors Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited distribution. Confirm RoHS compliance details and specific ordering suffixes against official onsemi documentation before procurement. Ensure compatibility with existing PCB footprints and design specifications during acquisition planning.

Supervisors Selection Notes

Select this component when a combined supervisory circuit and non-volatile memory solution is required for microcontroller systems. It is suitable for designs needing brown-out protection and 16K bytes of I2C-accessible storage. Consider the absence of a watchdog timer if that function is critical to the application requirements.
