CAT1320YI-28-GT3

Supervisors Overview

The CAT1320YI-28-GT3 is a Supervisory Circuit manufactured by onsemi, housed in an 8-TSSOP package. It features a threshold voltage of 2.8 V and monitors one input. The device supports manual reset functionality without a watchdog timer. Operating parameters include a maximum power dissipation of 1 W and a supply voltage range from 3 V to 5.5 V. Electrical characteristics specify an overvoltage threshold of 3 V and an undervoltage threshold of 2.85 V. The component operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates supervisory circuitry with manual reset capability for system monitoring
• Provides precise voltage threshold detection for power integrity management
• Designed for surface-mount installation in compact electronic assemblies

Supervisors Applications

• CPU voltage supervision in embedded systems
• Power-on reset generation for microcontroller units
• System monitoring in industrial control equipment

Supervisors Procurement Notes

Verify the specific suffix GT3 against the manufacturer's current datasheet to confirm pinout and electrical specifications match the design requirements. Confirm RoHS compliance status through official documentation before integration. Ensure the obsolete part status does not conflict with long-term production plans. Cross-reference the 8-TSSOP package dimensions with PCB footprint libraries to prevent assembly errors during manufacturing validation.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset is required for voltages between 3 V and 5.5 V. The 2.8 V threshold suits applications needing specific undervoltage protection levels. Consider the 8-TSSOP package for space-constrained designs requiring surface-mount technology. Evaluate the absence of a watchdog timer if automated timeout resets are necessary for the target application architecture.

Supervisors Part Context

This part belongs to the CAT1320 series of supervisory circuits from onsemi. It serves as a voltage monitor and reset generator for digital logic systems. The series typically offers various threshold options and package configurations to support diverse power management needs in consumer and industrial electronics.
