CAT1832V-GT3

Supervisors Overview

The CAT1832V-GT3 is a voltage supervisory circuit manufactured by onsemi, housed in an SOIC-8 surface-mount package. It monitors a single input channel with specified threshold voltages of 3.3 V and 5 V. The device features active low push-pull outputs and includes manual reset capability alongside a built-in watchdog timer. Key electrical parameters include a maximum supply voltage of 5.5 V, a minimum operating voltage of 1 V, and a typical quiescent current of 35 uA. The reset delay time is fixed at 1 second, with overvoltage and undervoltage thresholds documented at 2.97 V and 2.8 V respectively. It operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides manual reset functionality via dedicated pin
• Features active low push-pull output driver

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset circuitry
• Industrial control board monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for End-of-Life (EOL) notifications or Product Change Notices (PCN) prior to procurement, as discontinuance may affect long-term availability. Ensure the specific suffix matches design requirements.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog and manual reset is required. Verify that the 3.3 V and 5 V threshold options align with the target supply rails. Consider the SOIC-8 package constraints and the 1-second reset delay duration against system timing requirements. Evaluate the 35 uA quiescent current impact on overall power budget.

Supervisors Part Context

This part belongs to the CAT1832 series of voltage supervisors from onsemi. The series focuses on providing reliable power management protection for digital circuits. The CAT1832V-GT3 variant specifically denotes the SOIC-8 packaging and specific threshold configuration within this family of supervisory ICs designed for industrial and commercial applications.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic equivalents may lack the specific combination of watchdog and manual reset features. Ensure any replacement maintains compatibility with the SOIC-8 footprint and electrical specifications.
