Product details
Overview
ASL5115FHV/0Y from NXP Semiconductors is a direct-PWM matrix LED controller for automotive exterior lighting, delivering 12-channel switching with 1.5 A per switch, CAN-FD interface, and operation from –40 °C to +125 °C ambient. It drives up to 12 LEDs or segments at up to 57 V string voltage and supports dynamic PWM updates per channel for glare-free high-beam (ADB) and dynamic rear lighting systems.
For engineers reviewing the ASL5115FHV/0Y datasheet, ASL5115FHV/0Y pinout, ASL5115FHV/0Y application, or ASL5115FHV/0Y equivalent, key selection criteria include CAN-FD communication latency, 1.5 A per-channel current capability, HLQFP48 thermal performance, diagnostic flag clearing without POR, and Limp Home Mode activation during bus failure.
Technical Context
The ASL5115FHV/0Y implements a direct-PWM control architecture where the host microcontroller supplies real-time 12-bit PWM duty cycle values for each of its 12 output channels-no on-chip polynomial curve calculation. Each of the four configurable 3-switch blocks floats up to 60 V relative to ground and supports paralleling for higher current or redundancy.
It integrates a 200 MHz internal oscillator trimmed via CAN-ID messages (<0.25 % accuracy), eliminating external crystal requirements. Diagnostics include 6-bit NTC temperature feedback, 9-bit junction temperature reporting, open/short detection per LED, charge pump fault monitoring, and full CAN protocol error flagging-all accessible over the CAN-FD interface.

Applications
| Matrix High Beam (ADB) | Dynamic Rear Lighting |
|---|---|
Use Scenario: Pixelated headlamp system selectively blanks LED segments to avoid glare while maintaining full illumination around vehicles. IC Role / Device Role / Timing Role: ASL5115FHV/0Y acts as the final-stage LED driver, executing real-time PWM commands from ADAS ECU to control individual 1.5 A segments. Use Value: 12-bit PWM resolution and CAN-FD latency enable sub-10 ms pixel reconfiguration-meeting UNECE R149 glare-free timing requirements. | Use Scenario: Brake, turn, and position lights implement animated sequences (e.g., sweeping indicators, progressive stop lighting). IC Role / Device Role / Timing Role: ASL5115FHV/0Y serves as the distributed LED driver node, receiving synchronized animation frames over CAN-FD from body controller. Use Value: Four floating 3-switch blocks allow independent voltage domain control-enabling mixed-color (red/amber) rear arrays on shared PCBs. |
| Dynamic Cornering Light | Vehicle Welcoming Sequence |
Use Scenario: Low-beam LEDs dynamically steer illumination into curves based on steering angle and vehicle speed. IC Role / Device Role / Timing Role: ASL5115FHV/0Y drives dedicated cornering LED strings with precise current regulation and fast PWM response. Use Value: 1.5 A per channel and 57 V string capability support high-lumen white LEDs; thermal monitoring prevents overheating during sustained cornering operation. | Use Scenario: Exterior lighting executes choreographed light patterns (e.g., door-handle approach, walk-away fade) upon key fob detection. IC Role / Device Role / Timing Role: ASL5115FHV/0Y executes preloaded dimming sequences stored in host ECU memory, updating all 12 channels synchronously. Use Value: Standby current <1.35 mA and wake-on-CAN enable ultra-low-power welcome functions without battery drain concerns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar matrix LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ASL5115SHV | CAN (not CAN-FD); same pinout, package, and 1.5 A direct-PWM capability | Limited to 1 Mbit/s CAN; unsuitable for time-critical ADB systems requiring >2 Mbit/s bandwidth | Select ASL5115SHV only if legacy CAN infrastructure is fixed and bandwidth demand is ≤1 Mbit/s |
| ASL5015FHV | Smart PWM mode (on-chip polynomial dimming); identical CAN-FD interface and HLQFP48 package | Reduces MCU data load but lacks real-time per-frame control-less suitable for dynamic ADB pixel masking | Choose ASL5015FHV when system prioritizes reduced CAN traffic over frame-accurate dimming control |
Compared with ASL5115SHV, ASL5115FHV/0Y delivers higher CAN-FD bandwidth for deterministic ADB updates; versus ASL5015FHV, it trades precomputed dimming for full host-controlled PWM flexibility-making it optimal for adaptive lighting systems requiring real-time pixel reconfiguration.

FAQ
What is the primary interface protocol supported by the ASL5115FHV/0Y?
The ASL5115FHV/0Y uses a CAN-FD interface operating up to 5 Mbit/s, supporting both point-to-point and broadcast messaging across networks of up to 32 devices. This enables low-latency, deterministic control of all 12 channels-essential for adaptive driving beam (ADB) systems where timing precision is critical. The ASL5115FHV/0Y does not support SPI, I²C, or LIN interfaces.
Does the ASL5115FHV/0Y include built-in thermal protection?
Yes, the ASL5115FHV/0Y provides dual thermal monitoring: a 6-bit NTC input for external LED temperature sensing and 9-bit junction temperature feedback reported via CAN. It also features internal thermal shutdown at 175 °C junction temperature and supports dynamic current derating based on measured temperatures-ensuring robust operation in sealed headlamp enclosures.
How does the ASL5115FHV/0Y handle LED open-circuit or short-circuit faults?
The ASL5115FHV/0Y detects open and short faults per channel and reports them via dedicated CAN status flags. Crucially, it allows dynamic clearing of these flags-and resetting of internal MOSFETs-via CAN command without requiring a power-on-reset. In open-circuit conditions, it can optionally bypass the faulty LED to maintain partial array functionality.
What is the maximum LED string voltage the ASL5115FHV/0Y can drive?
The ASL5115FHV/0Y supports LED string voltages up to 57 V across its 12 high-side switches. Each of the four 3-switch blocks floats up to 60 V relative to ground, allowing flexible topologies such as multi-string parallel configurations or mixed-voltage domains-common in matrix headlamp designs combining white and amber LEDs.
Is the ASL5115FHV/0Y pin-compatible with other members of the ASL5xxx family?
Yes, all ASL5xxx variants-including ASL5115FHV/0Y-are pin-to-pin compatible within the same package type. The ASL5115FHV/0Y in HLQFP48 shares identical pinout with ASL5015FHV, ASL5115SHV, and ASL5015SHV, enabling hardware reuse across Smart PWM and Direct PWM variants and between CAN and CAN-FD versions.
