CAT1162WI-42-GT3

Supervisors Overview

The CAT1162WI-42-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU supervision applications. It features a single monitored input with an active high, active low, and open drain output configuration. The device includes manual reset functionality and operates within a supply voltage range of 2.7 V to 6 V. Key electrical parameters include a threshold voltage of 4.2 V, a reset delay time of 270 ms, and a maximum power dissipation of 1 W. It supports a watchdog timer and has no battery backup switch. The component is rated for operation between -40°C and +85°C and is housed in an SOIC-Wide-8 package.

Supervisors Feature Summary

• Integrates CPU supervision with manual reset capability
• Provides flexible output configurations including active high, active low, and open drain
• Includes integrated watchdog timer for system reliability

Supervisors Applications

• CPU voltage monitoring in embedded systems
• System reset generation for microprocessors
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply. Confirm RoHS compliance details through official datasheets. Ensure ordering suffix matches required packaging options such as reel or cut tape. Cross-reference manufacturer part numbers to avoid substitution errors during procurement.

Supervisors Selection Notes

Select this component when a single-input supervisor with configurable outputs is required. Consider the 270 ms reset delay and 4.2 V threshold for compatibility with target logic levels. Verify that the SOIC-Wide-8 package fits the design constraints. Check if the integrated watchdog meets timing requirements without external components.

Supervisors Part Context

This part belongs to the CAT1162 series of supervisory circuits from onsemi. It shares functional similarities with other parts in the family but differs in specific threshold voltages and EEPROM integration. The CAT1162 series is designed for general-purpose voltage monitoring in consumer and industrial electronics.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative supervisors based on threshold voltage, package type, and output configuration before substitution.
