CAT1162WI-45-GT3

Supervisors Overview

The CAT1162WI-45-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 2.7 V to 6 V and features a threshold voltage of 4.5 V. The device provides a reset delay time of 270 ms and supports manual reset functionality. It is housed in an 8-pin SOIC package suitable for surface mount technology. The component includes active high, active low, and open drain output types. It lacks a watchdog timer and battery backup switch. The operating temperature range extends from -40 °C to +85 °C.

Supervisors Feature Summary

• Integrates voltage supervision with non-volatile memory storage capabilities
• Provides flexible output configurations including active high, active low, and open drain options
• Supports manual reset input for system control

Supervisors Applications

• CPU power supply monitoring
• Embedded system reset generation
• Microcontroller voltage supervision

Supervisors Procurement Notes

Verify the exact suffix GT3 against official datasheets to confirm reel packaging specifications. Confirm RoHS compliance status through manufacturer documentation. Check current lifecycle status as obsolete parts may require alternative sourcing strategies. Ensure compatibility with existing PCB footprints for SOIC-8 packages.

Supervisors Selection Notes

Select this component when a combined supervisor and EEPROM solution is required. Verify that the 4.5 V threshold matches the target system voltage requirements. Consider the 270 ms reset delay for timing constraints. Evaluate the need for manual reset inputs versus automatic power-on reset only.

Supervisors Part Context

This part belongs to the CAT1162 series of supervisory circuits which integrate memory functions. It shares similarities with other CAT11xx models but differs in specific voltage thresholds and memory capacities. The WI suffix indicates wide body packaging variations compared to standard SOIC packages.
