EVQ7225-QJ-00A 16-Channel, Current Sink LED Driver with Adaptive Feedback Control (AFC) Evaluation Board
The EVQ7225-QJ-00A is an evaluation board designed to demonstrate the capabilities of the MPQ7225 and MPQ7225U, which are 16-channel, current sink LED drivers. Each channel is rated for up to 200mA of current, and 16 ICs can be cascaded together to create a 256-channel solution.
The MPQ7225 and MPQ7225U are optimized for animated or dynamic lighting applications. The devices employ a 12-bit pulse-width modulation (PWM) dimming register and 6-bit analog dimming register per channel, which enables separate control of each channel. The MPQ7225 and MPQ7225U are designed to function across distanced PCBs using a robust, high-speed differential interface, which is compatible with control area network (CAN) transceivers.
The MPQ7225 and MPQ7225U provide adaptive feedback control (AFC) to maximize system efficiency. The output voltage (VOUT) of the pre-regulator (e.g. buck voltage regulator) is adjusted in real time so that the voltage across the channels remains constant at the 300mV minimum headroom voltage.
The MPQ7225 and MPQ7225U provide a failsafe (/FS) indicator to support function safety in the system design. Full protection features include LED open protection, LED short protection, ISET pin open protection, ISET pin short protection, and over-temperature protection. If a fault occurs, the /FS pin is pulled low, and a matching fault register is set.
The MPQ7225 and MPQ7225U are available in a QFN-32 (5mmx6mm) package with wettable flanks. The MPQ7225 is available in AEC-Q100 Grade 1.
