The CAT4004AHU2-GT3 from ON Semiconductor is a constant current LED driver designed for applications requiring precise LED control. It provides four matched low dropout current sources, allowing for tight current matching across all channels. The device utilizes an external resistor (RSET) to set the current in the LED channels, offering flexibility in design.
This linear LED driver supports 32 distinct dimming levels through its EN/DIM logic input, enabling fine-tuned brightness control. With a low dropout voltage of 50 mV at 20 mA, it is suitable for direct battery-powered applications, including Lithium-ion battery systems. The CAT4004AHU2-GT3 also features thermal shutdown protection for enhanced reliability.
Packaged in an 8-UDFN (2x2 mm) with an exposed pad, this surface-mount component is designed for compact electronic devices. Its applications include LCD display backlights, cellular phones, and handheld devices where efficient and stable LED illumination is critical.
