The AW21104QNR is a 4-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 AW21104QNR can operate independently without processor control. The AW21104QNR is able to automatically enter power save mode, when LED outputs are not active and thus lowering current consumption. Four independent LED channels have accurate programmable current sinks, from 0mA to 25.5mA with 100μA steps and 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. The AW21104QNR has four pin-selectable I2C addresses. This allows connecting up to four parallel devices in one I2C bus. The device requires only one small, low-cost ceramic capacitor.
