CAT4109V-GT2 Description

Short technical summary and product information.

The CAT4109V-GT2 from ON Semiconductor is a versatile 3-channel constant-current LED driver designed for applications requiring precise LED control without an inductor. Each of the three independent current sinks can deliver up to 175 mA, with currents programmed via external resistors. This device supports individual PWM dimming control for each channel, allowing for dynamic lighting effects and precise brightness adjustment.

 

The driver operates with a logic supply voltage ranging from 3V to 5.5V and is compatible with LED strings up to 25V. Its low output voltage of 0.4V at 175mA contributes to power-efficient designs. The CAT4109V-GT2 includes an output enable (OE) pin for disabling channels and features thermal shutdown protection to prevent damage from overheating, with shutdown occurring above 150°C.

 

Packaged in a 16-lead SOIC surface-mount package, this LED driver is suitable for applications such as multi-color LED lighting, architectural lighting, LED signs and displays, and LCD backlights. It is Pb-free and Halogen-free, adhering to RoHS compliance standards.
