CAT1163WI-42-G

Supervisors Overview

The CAT1163WI-42-G is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It integrates a 16K I2C serial CMOS EEPROM with a precision reset controller and a watchdog timer. The device operates within a supply voltage range of 2.7 V to 6 V, featuring a fixed threshold voltage of 4.2 V and an overvoltage threshold of 4.5 V. It provides a manual reset input and offers configurable output types including active high, active low, and open drain configurations. The reset delay time is specified at 270 ms. The component is housed in an SOIC-Wide-8 surface-mount package and supports industrial temperature operation from -40°C to +85°C.

Supervisors Feature Summary

• Integrates 16K I2C serial EEPROM with precision reset controller and watchdog timer
• Configurable output options including active high, active low, and open drain
• Supports manual reset input functionality
• Industrial temperature range operation capability

Supervisors Applications

• CPU system supervision
• Microcontroller reset management
• Data storage in embedded systems via integrated EEPROM

Supervisors Procurement Notes

Verify the exact suffix 'G' against official onsemi documentation to confirm lead-free status and RoHS compliance specifications. Confirm package variant details as 'WI' denotes wide body SOIC. Check current lifecycle status as distribution data indicates potential discontinuation or limited availability for this specific part number.

Supervisors Selection Notes

Select this component when a combined power supervision and non-volatile memory solution is required for single-supply systems. Ensure the 4.2 V threshold aligns with the target logic voltage levels. Verify that the SOIC-Wide-8 package fits the PCB layout constraints compared to standard SOIC-8 variants.

Supervisors Part Context

This part belongs to the CAT1163 family of supervisory circuits originally developed by Catalyst Semiconductor and now produced by onsemi. The family combines power management functions with data storage capabilities. The 'WI' suffix typically indicates a wide-body SOIC package, while '42' specifies the undervoltage threshold voltage level.
