CAT3661HV3-GT2

Overview

The CAT3661HV3-GT2 is a single-channel LED driver IC from onsemi, utilizing a charge pump topology. It operates within an input voltage range of 2 V to 5.5 V and delivers a maximum output current of 5 mA. The device supports a supply voltage up to 5.5 V and generates an output voltage of 7 V. Operating frequencies are specified at 130 kHz. It functions reliably across a temperature range of -40°C to +85°C. The component is housed in a TQFN-16 package.

Feature Summary

Integrates a charge pump architecture for efficient low-power LED driving
Provides integrated fault protection and diagnostic capabilities
Designed specifically for ultra-low power applications such as portable handheld medical devices

Applications

Portable handheld medical devices
Button cell powered backlights
Ultra-low power LED applications

Procurement Notes

Verify the current lifecycle status before integration, as this component may be discontinued or subject to supply restrictions. Confirm RoHS compliance details through official documentation. Ensure the TQFN-16 package dimensions match the target PCB footprint. Validate that the 5 mA output current meets the specific LED requirements of the design. Check for any recent product change notices affecting manufacturing or specifications.

Selection Notes

Select this component for designs requiring minimal quiescent current and compact form factors. The single-channel configuration suits simple backlighting needs without complex multiplexing. Consider the 2 V minimum input voltage for battery-operated systems. The integrated charge pump eliminates external inductors, simplifying the bill of materials. Ensure the application environment stays within the specified -40°C to +85°C operating range.

Part Context

This part belongs to the CAT3661 series of low-power LED drivers. It is manufactured by onsemi and falls under the category of LED lighting drivers. The specific suffix GT2 indicates the tape and reel packaging format. It is distinct from multi-channel variants like the CAT3612 or CAT3648 series.
