【Dimmable LED Driver Evaluation Board】

Automotive lighting systems have evolved from basic illumination functions to become vital components enhancing both safety and aesthetics. NXP's Matrix LED Controller Evaluation Board provides designers with a powerful development tool for creating advanced vehicle lighting systems.

The ASL5015EVBMST evaluation board supports the ASL5015SHN matrix LED controller, which integrates 12 switches across four floating blocks, each capable of delivering up to 1.5A current output.

The on-board PWM controller features 12-bit resolution and automatic phase shift functionality, effectively mitigating peak current surges during switching transitions.

For more demanding lighting applications, NXP has also introduced the ASL61xxyHz series of enhanced matrix LED controllers. Supporting 16 LED channels, these controllers meet ASIL B safety ratings and satisfy automotive functional safety requirements.

Diagnostic capabilities provided by these evaluation boards include single LED open/short detection, direct NTC and ID resistor inputs, and a CAN FD interface, ensuring system reliability and communication flexibility.

【Automotive Sensor Evaluation Boards】

Within the automotive sensor domain, NXP offers multiple evaluation boards for processing diverse sensor data, including battery state monitoring and temperature sensing.

The RD33774ADSTEVB evaluation board is specifically designed for automotive battery controller applications, centred around the MC33774A device capable of monitoring up to 18 lithium-ion cells.

The board incorporates battery balancing resistors, with three 33-ohm resistors connected in parallel to each Cx pin, ensuring voltage equilibrium across all cells within the battery pack.

The on-board battery terminal low-pass filter, comprising a 10kΩ resistor and 0.047µF capacitor, effectively filters out noise interference to enhance measurement accuracy.

The evaluation board further integrates a 64Kb I²C EEPROM for storing user-defined calibration parameters, enhancing system customisation capabilities.

For temperature sensing, the board provides a general-purpose I/O low-pass filter for NTC connection and temperature measurement, supporting battery temperature monitoring functionality.

【Battery Management System Evaluation Board】

The battery management system constitutes a core component of electric vehicles, with NXP offering multiple evaluation boards to address diverse application requirements.

The RD33771CDSTEVB evaluation board centres on the MC33771C 14-channel battery cell controller, suitable for automotive and industrial lithium-ion battery applications.

This device performs ADC conversion on differential battery voltage/current, enabling battery charge coulomb counting and temperature measurement.

An on-board transformer facilitates high-speed isolated communication, supporting daisy-chain device connections for cascading multiple units.

The evaluation board also incorporates RGB LED indicators to display operational status, providing developers with intuitive system monitoring.

For high-voltage isolation applications, this board may be used in conjunction with the FRDM-DUALK3664EVB or FRDM-665SPIEVB, the latter incorporating an MC33664 isolation network high-speed transceiver that directly converts MCU SPI data bits into pulse-width information.
