The CAT4002BTD-GT3 from ON Semiconductor is a linear LED driver designed for applications such as LCD display backlights. It provides two matched low dropout current sources, each capable of delivering up to 25 mA.
The device features 32 distinct linear dimming levels, controlled via a 1-wire EZDim interface, allowing for precise brightness control. It requires no external RSET resistor, as the LED current is internally set. The low dropout voltage of 75 mV at 20 mA makes it suitable for direct connection to Lithium-ion batteries.
This LED driver operates over a temperature range of -40°C to 85°C and is available in a compact TSOT-23-6 package, suitable for surface mounting. It also includes thermal shutdown protection for enhanced reliability.
Typical applications include backlighting for cellular phones and digital still cameras, where efficient and controllable LED illumination is required.
