CAT4101TV

Overview

The CAT4101TV is a constant-current sink LED driver manufactured by onsemi, designed to drive strings of high-brightness LEDs with up to 1 A output current. It features a very low dropout voltage of 0.5 V at full load and requires no external inductor. The device supports an operating supply voltage range from 3 V to 5.5 V, with a nominal rating of 5 V. It operates within a temperature range of -40°C to 85°C and is housed in a TO-263-5 (D2PAK) surface-mount package.

Feature Summary

Constant-current sink topology for driving high-brightness LED strings
Inductor-less design simplifying circuit implementation
Configurable output current via external resistors
Low dropout voltage operation for improved efficiency

Applications

High-brightness LED lighting systems
Portable electronic device backlighting
General illumination applications requiring compact drivers

Procurement Notes

Verify the specific suffix (e.g., TV-T75) against the manufacturer's official datasheet to confirm package type, tape-and-reel specifications, and compliance status. Ensure the selected variant matches the required thermal performance and pinout configuration for the target PCB layout. Cross-reference RoHS and REACH compliance documents provided by onsemi for regulatory adherence.

Selection Notes

Select this component when an inductor-less solution is preferred for space-constrained designs. The fixed 1 A maximum current capability suits high-intensity LED arrays. Evaluate thermal dissipation requirements given the TO-263 package and tab connection. Confirm that the input voltage range aligns with the system power supply to maintain the specified low dropout performance under all operating conditions.

Part Context

The CAT4101 belongs to onsemi's portfolio of LED drivers utilizing BCD technology. This series focuses on efficient, compact solutions for portable and general lighting. The TV suffix typically denotes the TO-263-5 D2PAK package variant, distinguishing it from other form factors in the same functional family.
