CAT1640WI-42-GT3

Supervisors Overview

The CAT1640WI-42-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 3 V to 5.5 V and features a single monitored input with an active high or open drain output type. The device includes manual reset functionality and provides a reset delay time of 270 ms. It is housed in an SOIC-8 surface-mount package and supports industrial temperature ranges from -40°C to +85°C. This component lacks watchdog timer and battery backup switch capabilities, focusing on essential power supervision tasks.

Supervisors Feature Summary

• Provides reliable voltage supervision for CPU systems with manual reset capability
• Features flexible output options including active high and open drain configurations
• Operates across standard industrial temperature ranges for robust performance

Supervisors Applications

• CPU power supply monitoring in embedded systems
• Voltage supervision for microcontroller units
• Industrial control system power integrity checks

Supervisors Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited stock. Confirm RoHS compliance details through official datasheets before integration. Ensure ordering suffix matches required package and temperature specifications. Cross-reference manufacturer part numbers to avoid counterfeit risks. Validate application requirements against electrical parameters prior to procurement.

Supervisors Selection Notes

Select this component when simple voltage supervision with manual reset is required. Consider the SOIC-8 package size for space-constrained designs. Evaluate the 270 ms reset delay against system startup timing needs. Compare against similar parts if watchdog functionality is necessary later. Verify threshold voltage compatibility with target supply rails.

Supervisors Part Context

This part belongs to the CAT1640 series of supervisory circuits from onsemi. It shares design principles with related models like the CAT1641 but offers specific feature sets tailored for basic power monitoring. The series emphasizes reliability and ease of integration into standard digital logic environments.

Supervisors Replacement Considerations

Direct substitutes include CAT1640YI-42-GT3 (TSSOP-8 package) or CAT1641WI-42-T3 (similar function, different EEPROM integration). Verify pinout compatibility and electrical parameter equivalence before substitution.
