Product details

Overview

STEVAL-ILL072V1 from STMicroelectronics is an automotive-grade evaluation board implementing a single-channel, 1 A constant-current LED driver using the ALED6001 boost controller IC. It supports 8–24 V DC input, drives up to 10 white LEDs (40 V OVP), delivers 92% efficiency at 12 V_IN/32 V_OUT/1 A, and enables PWM or analog (10:1) dimming for interior/exterior lighting.

For engineers reviewing the STEVAL-ILL072V1 datasheet, STEVAL-ILL072V1 pinout, STEVAL-ILL072V1 application, or STEVAL-ILL072V1 equivalent, this board provides a validated reference design for DTRL, cabin ambient lighting, map lights, and other automotive LED string applications requiring fault detection, high efficiency, and AEC-Q200-compliant components.

Technical Context

The board implements a synchronous boost topology centered on the ALED6001, which integrates a 500 kHz current-mode PWM controller, gate driver, LDO3 bias supply, and comprehensive protection circuitry including open-LED, feedback disconnection, and overcurrent detection with XFAULT flag output.

Dimming is implemented via two independent paths: a dedicated ADIM pin accepting 0–2.5 V analog control (10:1 range), and PWMI/PWMO pins supporting external PWM signals (0–100% duty cycle). Output voltage regulation uses resistive divider feedback (VFBP/VFBN) with 40 V overvoltage protection threshold.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	8 V – 24 V DC: Supports full automotive battery range including cold-crank (8 V) and load-dump (24 V) conditions.
Output Current	1000 mA constant: Delivers stable current to single LED string regardless of forward voltage variation across temperature and aging.
Switching Frequency	500 kHz: Enables compact magnetics (L1/L2) and low EMI while maintaining high efficiency in space-constrained automotive modules.
LED String Limit	Up to 10 white LEDs: Corresponds to ~32 V typical forward voltage, aligned with 40 V OVP threshold for safety margin.
Efficiency	92% @ 12 V_IN, 32 V_OUT, 1 A: Minimizes thermal stress and power loss in enclosed headlamp or console housings.
Dimming Methods	PWM (0–100%) + analog (10:1): Enables flexible integration with vehicle body controllers using either digital or analog interfaces.
Protections	Open-LED, feedback disconnect, LED overcurrent: Faults trigger XFAULT pin assertion and disable output to prevent damage during field operation.

FAQ

What is the maximum LED string voltage supported by STEVAL-ILL072V1?

The board supports up to 40 V output due to the ALED6001's internal overvoltage protection threshold. With typical white LED V_F ≈ 3.2 V, this allows driving up to 10 LEDs in series (32 V nominal), leaving 8 V margin for tolerance and temperature drift.

Does STEVAL-ILL072V1 support analog dimming only, or both analog and PWM?

It supports both: analog dimming via the ADIM pin (0–2.5 V input yields 10:1 brightness range), and PWM dimming via the PWMI input (0–100% duty cycle). The board includes jumpers and test points (TP2, TP3) to configure either mode independently.

Is STEVAL-ILL072V1 qualified for automotive use?

Yes - all passive and active components meet AEC-Q200 requirements, and the board implements automotive-specific protections including open-LED detection, feedback line monitoring, and overcurrent shutdown. It is intended for use in DTRL, interior lighting, and other automotive lighting systems.

Can STEVAL-ILL072V1 drive multiple independent LED strings?

No - it is a single-channel solution designed exclusively for one LED string. The ALED6001 IC does not support multi-string operation; parallel strings would require external current balancing and are not validated on this board.
