ASL5xxxyHz Matrix LED Controller (MLC) Rev. 1.0 — 24 May 2019 1 Product brief General description The ASL5xxxyHz family is a fully featured and flexible Matrix LED Controller (MLC). It provides a cost effective design solution, specifically targeting advanced automotive exterior lighting applications. The family consists of part numbers with different maximum currents and different driving modes, Smart and direct PWM. Smart PWM part numbers determine PWM dimming duty cycle from information stored inside the MLC in the form of dimming polynomial curve coefficients. These coefficients are programmable by the customer according to the dimming profile they would like to see. The MLC uses these polynomial coefficients to calculate the PWM duty cycle to 12bit resolution. The MLC also provides the capability to increase the speed of the PWM dimming curve dynamically or sequence several PWM dimming curves together. It is possible to store polynomials for up to eight PWM dimming curves. By storing these polynomial coefficients internally, it is not necessary for the microcontroller to send updated PWM dimming information to each LED switch continuously. Instead, the microcontroller selects the PWM curve and LED to which it must be applied. Therefore, the PWM dimming information from the microcontroller is reduced, which reduces the volume of data transfer from the microcontroller to the MLC. The MLC also provides the functionality to correct for LED brightness variations. This feature is especially useful to ensure a homogenous light output from LEDs that have luminance variations with the same LED current. The MLC has many diagnostic features, including: • • • • • • • • • Direct NTC feedback for monitoring the LED temperature Direct identification resistor input for PCB characterization Single LED open/short detection and protection Internal IC junction temperature monitoring Power-on-Reset (POR) monitoring; mandatory for off-board configuration and following safety requirements Power OK bit (POK) to ensure that the complete MLC is working as expected External components (NTC, ID resistor, charge pump capacitor) monitoring and fail detection Full communication diagnosis, including flagging illegal actions Possibility to clear Open Circuit (OC) and Short Circuit (SC) flags and reset the internal mosfets dynamically and without a need of a power-on-reset All this diagnostic information is available to the microcontroller via the MLC interface. A microcontroller controls the MLC through a high-speed serial CAN interface. Through this interface, the microcontroller can control up to 32 MLCs, enabling control of up to 384 LEDs or segments. The MLC has an internal 200 MHz oscillator that avoids the need of an external quartz (reducing system cost and providing better EMC behavior) for synchronization and clock ASL5xxxyHz NXP Semiconductors Matrix LED Controller (MLC) generation. All the internal clocks are synchronized with the internal oscillator and the trimming is done via the CAN message (CAN-ID). This process allows for a very accurate clock (accuracy < 0.25 %). The MLC can be mounted close to the LEDs on an IMS PCB. Because the pinning has been optimized to avoid any crossing tracks, a single-layer PCB can be used. The ASL5xxxyHz family is available in automotive-qualified, thermally enhanced, 36-pin HVQFN and 48-pin HLQFP packages. The device is designed to meet the stringent requirements of automotive applications, being fully AEC Q100 grade 1 and AEC Q006 qualified. It operates over the –40 °C to +125 °C ambient temperature range. The Matrix LED Controller (MLC) also offers the possibility to be driven in direct PWM mode. In this mode, the microcontroller needs to update the PWM value in every channel with a certain cycle, determined by the system specifications. These part numbers, ASL5115yHz and ASL5108yHz, also offer 12-bit resolution to ensure a smooth dimming performance to avoid glitches in the output light. The MLC family also offers two different maximum currents per switch. Part numbers ASL5008yHz and ASL5108yHz offer a maximum current per switch of 0.8 A. Part numbers ASL5015yHz and ASL5115yHz offer a maximum current per switch of 1.5 A. All part numbers are pin-to-pin compatible, which offers a completely scalable and flexible system solution that can be adapted to any system requirements.
