Lighting Management Unit
The AS3665 is a capacitive low noise charge pump with 9 current sources. The charge pump automatically switches between 1:1 and 1:1.5 modes. The connected current sources have a very low voltage compliance to improve efficiency of the whole system. Three current sources have the possibility to operate either from VBAT or VCP (especially useful for red LEDs).
The internal control is done by command based pattern generators implemented by three sequencers. These commands are optimized for lighting applications (e.g. ramp up brightness logarithmically). It includes high level commands like conditionals jumps and variables. Any of the three sequencers can be dynamically mapped to any of the 9 PWM generators for the LEDs.
The AS3665 supports an audio input and sophisticated light patterns can be controlled by internal digital filters.
The AS3665 is controlled by I2C mode. Synchronization over several AS3665 is possible by the TRIG pin.
The AS3665 is available in a space-saving WL-CSP-25(2.5x2.5mm) 0.5mm pitch and operates over the -30℃ to +85℃ temperature range.
