The MPQ7225B-AEC1 is a 16-channel current-sink LED driver. Each channel is rated for up to 200mA of current, and 16 ICs can be cascaded together to create a 256-channel solution. 

The device is optimized for animated or dynamic lighting applications. It employs 12-bit pulse-width modulation (PWM) dimming and 6-bit analog dimming register per channel, with individual control of each channel. The MPQ7225B-AEC1 features a universal asynchronous receiver-transmitter (UART) communication protocol, allowing for robust communication from a host MCU.
It features Adaptive Feedback Control (AFC^TM) to maximize system efficiency. The output voltage of the pre-regulator (i.e. buck voltage regulator) is adjusted in real time so that the voltage across the channels is kept at a minimum value (typically 300mV headroom at 200mA). Frequency spread spectrum (FSS) optimizes EMC performance. The LED current’s ramping rate and the phase shift between channels can be digitally configured as well. 

The MPQ7225B-AEC1 can aid a system design for functional safety with a failsafe (/FS) indicator. The full protection suite includes LED open/short protection, ISET pin open/short protection, and thermal shutdown. If a fault occurs, the fault indicator pulls low and the matching fault register is set. 

The MPQ7225B-AEC1 is available in a QFN-32 (5mmx6mm) package, and is AEC-Q100 qualified.
