CAT1162WI-42-T3

Supervisors Overview

The CAT1162WI-42-T3 is a CPU supervisory circuit manufactured by onsemi, designed to monitor voltage levels and provide reset signals for microprocessor systems. It integrates a 16K EEPROM for non-volatile data storage within a single SOIC-8 package. The device operates with a maximum supply voltage of 6 V and features a threshold voltage of 4.2 V. It includes a manual reset input and an open-drain output type. The component supports a watchdog timer function and offers active high, active low, or open drain outputs. It functions within a temperature range of -40°C to +85°C and consumes 3 mA of operating current.

Supervisors Feature Summary

• Integrates 16K EEPROM for persistent data retention alongside voltage supervision
• Provides configurable output states including active high, active low, and open drain options
• Includes manual reset capability for system control flexibility
• Supports watchdog timer functionality for automated fault recovery

Supervisors Applications

• CPU supervisor circuits requiring integrated memory
• Systems needing manual reset inputs
