CAT150169MWI-GT3

Supervisors Overview

The CAT150169MWI-GT3 is a voltage supervisory circuit manufactured by onsemi, designed to monitor system power integrity. It integrates a 16-kbit SPI serial EEPROM for non-volatile data storage within a single SOIC-Wide-8 package. The device monitors one input with an undervoltage threshold ranging from 4.25 V to 4.5 V and features a push-pull output. It operates between 2.5 V and 5.5 V with a reset delay of 20 us. The component supports industrial temperatures from -40°C to +85°C and consumes 2 mA during operation.

Supervisors Feature Summary

• Integrates a 16-kbit SPI serial EEPROM for onboard configuration or status data retention
• Provides dedicated voltage supervision with a fixed reset delay time
• Delivers active high/low push-pull output signals for direct logic interfacing

Supervisors Applications

• System power monitoring in embedded controllers
• Configuration storage for voltage supervisor circuits
• Industrial equipment requiring integrated supervision and memory

Supervisors Procurement Notes

Verify the specific suffix MWI against the official datasheet to confirm package dimensions and thermal characteristics. Confirm availability status as distribution channels may indicate limited supply or end-of-life conditions. Ensure the selected variant matches the required operating temperature range and voltage thresholds for the target application environment.

Supervisors Selection Notes

Select this component when a combined voltage supervision function and small-scale non-volatile memory are required in a compact footprint. The integrated EEPROM eliminates the need for separate memory chips, reducing board space. Verify that the 20 us reset delay and 4.25 V to 4.5 V threshold align with the system's power rail stability requirements.

Supervisors Part Context

This part belongs to the CAT15016 series of supervisory circuits featuring integrated memory. Unlike standard supervisors, it combines power management IC functions with data storage capabilities. The SOIC-Wide-8 package offers a wider pin pitch compared to standard SOIC-8, facilitating easier surface-mount assembly while maintaining a low profile for dense PCB layouts.

Supervisors Replacement Considerations

Check for CAT150169MWT3 if a TSSOP package is preferred instead of SOIC-Wide-8. Verify functional compatibility regarding the 16K EEPROM size and SPI interface protocol before substitution.
