WD3153D-10/TR

The WD3153 is a 3-channel LED driver designed to produce variety of lighting effects. The device has a program memory for creating variety of lighting sequences. When the program memory has been loaded, the WD3153 can operate independently without processor control. Three independent LED channels have accurate programmable current sinks, from 0mA to 25mA with 5 steps and 8-bit flexible PWM control. Each channel can be configured into each of the three program execution engines. Program execution engines have program memory for creating desired lighting sequences with PWM control.
