1 / 19 page  WD3153 Will Semiconductor Ltd. 1 Nov. 2017 - Rev. 1.2 WD3153 3-Channel LED Driver Descriptions 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. Features Supply voltage: 2.4V to 5.5V Three independently programmable LED outputs with 8-bit PWM control and 3-bit current setting (from 0mA to 25mA) Autonomous operation with three program execution engines Direct I 2C register control for lighting I 2C Compatible Interface Power supply support 1.8V to 5.5V Data transfers up to 400kbps INTN interrupt function Typical LED output saturation voltage 80mV LED output current accuracy ±2% and current matching ±1% Built-in oscillator with ±5% accuracy Support charging indication under low battery condition Directly start up breathing light on LED0 Breathing period: 5s or continuous Low power consumption Operating current: 80uA Less than 1uA in shut down mode Http//:www.sh-willsemi.com 1 4 5 2 GND 3 10 7 6 9 8 LED1 LED2 LED0 INTN VCC SDA CHRG SCL SET NC Pin configuration (Top view) 3 1 5 3 WDYW DFN2X2-10L 3153 = Device code Y = Year code W = Week code Marking Order information Device Package Shipping WD3153D-10/TR DFN2X2-10L 3000/Reel&Tape Operating temperature: -40℃ to 85℃ ESD HBM 4kV DFN2X2-10L package Applications Smart Phones Tablets Indicator lights |
