CAT1640WI-30-GT3

Supervisors Overview

The CAT1640WI-30-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It features a single monitored input with an active low, open-drain output type and supports manual reset functionality. The device operates within a supply voltage range of 3 V to 5.5 V, with specific threshold voltages at 3 V, 3.3 V, and 5 V. Key electrical parameters include a reset delay time of 270 ms, a maximum power dissipation of 1 W, and a working supply current of 3 mA. It is housed in an SOIC-8 surface-mount package and functions reliably across an operating temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the part status as End-of-Life (EOL) prior to procurement planning. Ensure compliance with RoHS directives and material composition declarations. Validate package markings against official datasheets to prevent counterfeit substitution. Review technical documentation for any specific handling or storage requirements associated with the SOIC-8 package.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with manual reset is required for CPU monitoring. Consider the 270 ms reset delay and open-drain output characteristics for timing compatibility. Evaluate the 3 V to 5.5 V operating range against the target system's power rails. Assess the SOIC-8 package size constraints relative to the PCB layout. Verify that the absence of a watchdog timer meets the application's safety requirements.

Supervisors Part Context

This component belongs to the CAT1640 series of supervisory circuits from onsemi, which are part of the broader Treo platform portfolio. The Treo platform utilizes BCD 65nm technology to deliver reliable power management and standard product solutions. This series focuses on providing robust voltage monitoring and reset generation capabilities for industrial, automotive, and consumer electronics applications requiring stable system operation.

Supervisors Replacement Considerations
