Product details
Overview
ASL5115SHV from NXP Semiconductors is a 48-pin HLQFP automotive-grade Matrix LED Controller (MLC) supporting direct PWM mode with 12-bit resolution, 1.5 A per switch, and CAN interface. It drives up to 12 LEDs/segments at up to 57 V string voltage and operates from –40 °C to +125 °C ambient, targeting advanced exterior lighting including ADB high/low beams and dynamic rear lights.
For engineers reviewing the ASL5115SHV datasheet, ASL5115SHV pinout, ASL5115SHV application, or ASL5115SHV equivalent, this device delivers deterministic direct-PWM control with integrated diagnostics, thermal monitoring via NTC input, and system-level fault management for safety-critical automotive lighting systems.
Technical Context
The ASL5115SHV implements a 12-channel LED driver architecture organized in four configurable blocks of three switches each, where each block floats up to 60 V relative to ground and supports paralleling. It uses a high-speed CAN interface (not CAN-FD) for microcontroller communication and supports broadcast messaging to reduce bus load across up to 32 daisy-chained MLCs.
All internal clocks derive from an on-chip 200 MHz oscillator trimmed via CAN-ID messages (<0.25 % accuracy), eliminating external quartz. The device integrates charge pump failure safe operation (CPFSO), Limp Home Mode (LHM) on communication loss, and real-time LED open/short detection with bypass capability on open faults.

Applications
| Matrix High Beam (ADB) | Dynamic Rear Lighting |
|---|---|
Use Scenario: Adaptive driving beam system selectively blanks LED segments to avoid glare while maintaining maximum illumination around vehicles. IC Role / Device Role / Timing Role: ASL5115SHV acts as the high-voltage, high-current LED switch matrix controller, executing real-time PWM updates from ADAS ECU via CAN. Use Value: 12-bit direct PWM resolution and 1.5 A per channel enable fine-grained pixel-level control of up to 12 independently dimmed zones per controller. |
Use Scenario: Brake, turn, and position lights dynamically animate using programmable LED sequences synchronized across vehicle rear. IC Role / Device Role / Timing Role: ASL5115SHV serves as the segment driver for multi-zone rear lamp modules, receiving CAN commands for timing-critical animation patterns. Use Value: Broadcast messaging support and 32-device CAN network scalability allow coordinated animations across multiple lamp units with minimal latency. |
| Dynamic Cornering Light | Welcoming Lighting Sequence |
Use Scenario: Front cornering lamps activate additional LED segments during low-speed turns to illuminate curb-side road area. IC Role / Device Role / Timing Role: ASL5115SHV controls dedicated cornering LED strings, triggered by steering angle and vehicle speed signals routed through CAN. Use Value: Integrated NTC_IN and ID_RES inputs allow thermal derating and board-specific calibration - critical for compact, thermally constrained front-end modules. |
Use Scenario: Vehicle illuminates sequential LED patterns upon approach or door unlock to enhance brand recognition and user experience. IC Role / Device Role / Timing Role: ASL5115SHV executes preloaded lighting sequences stored in host ECU memory, updating all 12 channels synchronously via CAN broadcast. Use Value: On-chip 200 MHz oscillator ensures precise inter-channel phase shifting - eliminates visible flicker during fast-moving welcome animations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar matrix LED control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ASL5115SHN | HVQFN36 package (SOT1092-4); identical electrical specs and CAN interface; no leaded pins | Better suited for space-constrained, high-density PCB layouts where thermal pad soldering is preferred over gull-wing reflow | Select ASL5115SHN when board area is limited and automated optical inspection (AOI) compatibility is prioritized over manual rework accessibility. |
| ASL5115FHV | HLQFP48 package with CAN-FD interface; same pinout and drive capability; supports higher data rate and extended data length | Required for next-gen vehicle architectures adopting CAN-FD for lighting domain controllers with tighter latency budgets | Choose ASL5115FHV only if the host ECU implements CAN-FD and system-level bandwidth exceeds classical CAN limits. |
Compared with ASL5115SHN and ASL5115FHV, the ASL5115SHV offers classical CAN compatibility in a leaded HLQFP package-ideal for production stability, thermal reliability in high-power exterior modules, and ease of rework in Tier 1 manufacturing environments.

FAQ
What is the primary interface protocol supported by the ASL5115SHV?
The ASL5115SHV supports Classical CAN (ISO 11898-2) as its sole serial interface - it does not implement CAN-FD. Communication occurs over differential CANH/CANL lines at standard automotive bit rates (e.g., 500 kbps), enabling daisy-chained networks of up to 32 devices with broadcast message capability. This interface is used for configuration, real-time PWM updates, and diagnostic readback in the ASL5115SHV.
Does the ASL5115SHV include built-in protection against LED open or short circuits?
Yes, the ASL5115SHV provides per-channel LED open-circuit and short-circuit detection with automatic response. Upon detecting an open circuit, it activates a bypass path to maintain current flow through remaining LEDs in the string. Short-circuit faults trigger immediate shutdown of the affected channel and flag reporting via CAN. These protections are hardware-implemented and operate independently of firmware, ensuring robustness in the ASL5115SHV.
What is the maximum LED string voltage the ASL5115SHV can handle?
The ASL5115SHV supports LED string voltages up to 57 V - verified under recommended operating conditions. Each of its 12 output channels is rated for operation within this range, and the four configurable 3-switch blocks can float up to 60 V relative to ground, allowing series-connected LED strings to be driven directly without external high-voltage level-shifting circuitry in the ASL5115SHV.
How does the ASL5115SHV manage thermal performance in automotive environments?
The ASL5115SHV incorporates multiple thermal safeguards: an internal junction temperature sensor reporting 9-bit data over CAN, direct NTC_IN input for LED temperature monitoring (6-bit resolution), and thermal derating logic that reduces output current above defined thresholds. Its HLQFP48 package features an exposed thermal pad and is qualified to AEC-Q100 Grade 1 (–40 °C to +125 °C ambient), ensuring reliable operation in under-hood and exterior lighting locations for the ASL5115SHV.
Is the ASL5115SHV pin-compatible with other members of the ASL5xxx family?
Yes, all ASL5xxx part numbers - including ASL5115SHV, ASL5115SHN, ASL5015SHV, and ASL5108SHV - share identical pinouts within the same package type. ASL5115SHV (HLQFP48) is pin-to-pin compatible with ASL5015SHV and ASL5108SHV, enabling hardware reuse across current-rating and mode variants. However, ASL5115SHV is not pin-compatible with HVQFN-packaged variants due to differing land patterns and thermal pad configurations.
