2 / 69 page  NXP Semiconductors ASL5xxxyHz Matrix LED Controller (MLC) ASL5xxxyHz All information provided in this document is subject to legal disclaimers. © NXP B.V. 2019. All rights reserved. Product data sheet Rev. 2.1 — 5 February 2019 2 / 69 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. |
