CAT4134HV2-T2

Overview

The CAT4134HV2-T2 is a dual-channel LED driver IC manufactured by onsemi, utilizing Boost topology. It operates within an input voltage range of 2.8 V to 4.2 V and supports output currents up to 250 mA for high-level outputs and 5 mA for low-level outputs. The device is housed in a TDFN-12 surface-mount package and functions reliably across a temperature range of -40°C to +85°C. This component is designed for efficient LED lighting applications requiring precise current regulation.

Feature Summary

Dual-channel architecture for independent LED control
Boost converter topology for voltage step-up applications
Integrated thermal protection mechanisms

Applications

Portable LED lighting systems
Battery-powered illumination devices
General solid-state lighting solutions

Procurement Notes

Verify the specific suffix 'T2' against official datasheets to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status through manufacturer documentation. Check current lifecycle status as availability may vary. Ensure compatibility with existing board layouts regarding the TDFN-12 footprint before procurement.

Selection Notes

Select this component when designing circuits requiring dual-channel boost regulation from low-voltage sources. Consider the 250 mA maximum output capability for LED string sizing. Evaluate the TDFN-12 package size constraints against available PCB space. Verify that the operating temperature range meets environmental requirements for the target application.

Part Context

This part belongs to the CAT4134 series of LED drivers from onsemi. The series focuses on providing efficient power management for LED arrays in portable and battery-operated devices. The HV2 variant indicates specific electrical characteristics optimized for higher voltage headroom compared to standard variants.

Replacement Considerations

Check for direct substitutes within the CAT4134 family. Verify pinout compatibility if considering alternative packages. Review updated datasheets for any functional changes in newer revisions.
