The EVQ3322-QKE-00A evaluation board is designed to demonstrate the capabilities of the MPQ3322-AEC1, a 24-channel LED driver with a 24V voltage rating and maximum 100mA current source. It is designed to drive LEDs as backlighting, RGB lighting, and interior ambient lighting in automotive LCD panels and lamps. 

The MPQ3322-AEC1 employs a low headroom voltage to regulate the LED current (I_LEDx), and provides the feedback voltage (V_FB) for previous power stages to optimize the output voltage (V_OUT) for LED strings, which helps achieve higher system efficiency. 

The device supports independent 12-bit pulse-width modulation (PWM) and 6-bit analog dimming for each channel via the based controller area network (CAN) differential interface. The resistor on the ISET pin (R_ISET) configures the maximum I_LEDx amplitude. 

Robust protections are included to guarantee safe device operation. These protections include LED open protection, LED short protection (threshold configurable via internal registers), and over-temperature protection (OTP). All fault statuses can be read via the CAN interface. Additionally, the failsafe function ensures that MPQ3322-AEC1 remains operating in a preset state if communication information is lost. 

The FF pin and single lamp mode (SLM) support single-IC and multi-IC applications for two fault statuses. In the event of a failure, the IC either turns off only the failed LED string or shuts down all channels if one channel has failed. 

The MPQ3322-AEC1 is available in a QFN-40 (6mmx6mm) package, and is available in AEC-Q100 Grade 0.
