The MPQ7222-AEC1 is a 24-channel current sink LED driver. Each channel is rated for up to 100mA of current, and 16 ICs can be cascaded together to create a 384-channel solution, which makes the MPQ7222-AEC1 ideal for automotive exterior rear lighting.

The MPQ7222-AEC1 is optimized for animated or dynamic lighting applications. It employs a 12-bit pulse-width modulation (PWM) dimming register and 6-bit analog dimming register per channel, with individual control of each channel. The MPQ7222-AEC1 is designed to function across distanced PCBs with a robust, high-speed, CAN-compatible differential interface.

The MPQ7222-AEC1 features adaptive feedback control (AFC) to maximize system efficiency. The output voltage of the pre-regulator (e.g. buck voltage regulator) is adjusted in real time so that the voltage across the channels is kept at a minimum value (500mV headroom at 100mA).

The MPQ7222-AEC1 can aid a system design for functional safety with its failsafe (/FS) indicator. Protection features include LED open/short protection, single LED short protection, and over-temperature protection (OTP). The failsafe function keeps the MPQ7222-AEC1 operating via a preset state if the CAN communication is lost.

The fault flag and single-lamp mode (SLM) support applications featuring multiple ICs for two fault statuses: only turn off the failed LED (one-fail, others-on), or shut down all channels if one channel fails (one-fail, all-fail).

The MPQ7222-AEC1 is available in a QFN-40 (6mmx6mm) package. It is available in AEC-Q100 Grade 1.
