CAT4103V-GT2

Overview

The CAT4103V-GT2 is a three-channel LED driver IC designed for RGB LED applications, manufactured by onsemi. It operates within an input voltage range of 3 V to 5.5 V and delivers high-level output currents up to 200 mA and low-level currents up to 175 mA per channel. The device utilizes a four-wire interface for control and is housed in a 16-lead SOIC package. It supports surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides independent current regulation for three distinct LED channels suitable for RGB color mixing
• Utilizes a four-wire serial interface for digital control and data transmission
• Integrates protection mechanisms against open LED conditions to ensure system reliability

Applications

• RGB LED lighting systems
• Backlighting drivers for displays
• General-purpose multi-channel LED illumination

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors due to the presence of counterfeit risks in the market. Confirm that the specific suffix GT2 matches the required reel packaging specifications. Ensure compatibility with the intended PCB footprint and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for driving multiple RGB LEDs from a single low-voltage supply is required. Consider the 200 mA maximum output capability to ensure it meets the forward current demands of the target LEDs. Evaluate the SOIC-16 package dimensions against available board space constraints.

Part Context

This part belongs to the CAT4103 series of LED drivers from onsemi. It is specifically engineered for applications requiring precise current control across multiple channels without the complexity of external boost converters. The design focuses on simplifying the bill of materials for standard RGB LED implementations.
