CAT1320WI-28-GT3

Supervisors Overview

The CAT1320WI-28-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 threshold voltage of 2.8 V. The device supports manual reset functionality and monitors a single input. It is housed in an SOIC-8 surface-mount package and operates at a working power current of 3 mA. The component is rated for an operating temperature range from -40°C to +85°C, with a maximum power dissipation of 1 W.

Supervisors Feature Summary

• Provides voltage supervision for central processing units
• Supports manual reset control
• Monitors a single voltage input channel

Supervisors Applications

• CPU voltage monitoring systems
• Embedded system power management
• Industrial control unit supervision

Supervisors Procurement Notes

Verify the specific suffix GT3 against official onsemi documentation to confirm tape-and-reel packaging specifications. Ensure the SOIC-8 package variant matches design constraints. Cross-reference the 2.8 V threshold requirement with system voltage rails. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset capability is required for 3 V to 5.5 V systems. The 2.8 V threshold suits applications needing precise low-voltage detection. The SOIC-8 package offers a compact solution for space-constrained PCB layouts. Verify that the 3 mA operating current aligns with system power budget requirements.

Supervisors Part Context

This part belongs to the CAT1320 series of voltage supervisors from onsemi. The series focuses on reliable power management for digital logic circuits. The WI suffix indicates the SOIC-8 package type, while the 28 denotes the specific threshold voltage setting. This family provides essential protection against unstable power conditions in embedded environments.

Supervisors Replacement Considerations

Check for CAT1320 variants with different threshold voltages if system rail levels change. Consider other onsemi supervisors like the CAT1320 series members for pin-compatible alternatives. Verify interface compatibility if manual reset timing requirements differ significantly from the standard specification.
