Product details
Overview
AL5809-60QP1-7 from Diodes Incorporated is a two-terminal, AEC-Q100 Grade 3 qualified constant current linear LED driver in PowerDI123 (Type B) package, delivering 60 mA ±5% current accuracy over -40°C to +150°C junction temperature, with 2.5 V to 60 V operating voltage range and 1.5 V turn-on threshold-designed for high-side or low-side LED string driving in automotive interior lamps and parking lights.
For engineers reviewing the AL5809-60QP1-7 datasheet, AL5809-60QP1-7 pinout, AL5809-60QP1-7 application, or AL5809-60QP1-7 equivalent, key selection criteria include its fixed 60 mA output, 60 V max input-output rating, thermal shutdown at +165°C, ±5% current tolerance across temperature, and compatibility with PWM dimming via external MOSFET switching on the OUT pin.
Technical Context
The AL5809-60QP1-7 implements a precision current mirror architecture with an internal fixed reference resistor to set 60 mA nominal output, achieving 20 ppm/°C temperature stability. Its low-dropout regulator powers the control block independently of VIN–OUT variation.
It operates as a two-terminal constant current regulator (CCR), supporting both high-side and low-side configurations without polarity reversal-current flows unidirectionally from IN to OUT, with startup triggered at ~1.5 V across terminals and full regulation established above 2.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| LED Output Current | 60 mA ±5% at +25°C; 54–66 mA over -40°C to +150°C - ensures stable illumination intensity across automotive ambient extremes. |
| Operating Voltage Range | 2.5 V to 60 V between IN and OUT - supports 2–15 white LEDs in series under 12 V/24 V automotive systems with transient immunity up to 60 V. |
| Thermal Shutdown Threshold | +165°C with +30°C hysteresis - prevents permanent damage during overload or poor PCB thermal design while enabling automatic recovery. |
| Current Line Regulation | ±1%/V over 2.5–60 V - minimizes LED brightness drift during battery voltage fluctuations (e.g., 9–16 V cranking/start-stop). |
| Power Dissipation Limit | 1.53 W on 50.8 mm × 50.8 mm GETEK PCB - defines maximum continuous drive capability before thermal derating begins. |
| ESD Protection | HBM: 4 kV, MM: 400 V, CDM: 1 kV - meets automotive handling robustness requirements without additional protection circuitry. |
Pinout & Package
Package: PowerDI123 (Type B), surface-mount, thermally enhanced with exposed cathode pad; dimensions: 3.70 mm × 2.80 mm × 1.78 mm (L × W × H); θJA = 81.4°C/W on 50.8 mm × 50.8 mm GETEK PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | LED Current Input Terminal | Current enters here; connects to LED cathode in low-side config or LED anode in high-side config - determines current direction and system topology. |
| OUT (Pin 2) | LED Current Output Terminal | Current exits here; connects to LED anode in low-side config or LED cathode in high-side config - forms bidirectional current path with IN for flexible placement. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 60 mA Output | Eliminates external current-setting resistor - reduces BOM count, PCB area, and calibration complexity in cost-sensitive automotive lighting modules. |
| AEC-Q100 Grade 3 Qualification | Validated for -40°C to +85°C ambient operation - enables use in under-hood and exterior lighting where extended temperature range is required. |
| Two-Terminal High/Low-Side Flexibility | No ground-referenced control pins - simplifies layout by allowing direct series insertion into LED string regardless of power rail position. |
| PWM Dimming Support | Compatible with external MOSFET switching on OUT pin at 100–200 Hz, 5–95% duty cycle - enables analog-like brightness control without modifying driver IC. |
| Robust Transient Immunity | 60 V max VIN–OUT rating withstands load-dump transients per ISO 7637-2 - avoids need for upstream TVS clamping in many automotive designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar constant current LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL5809-50QP1-7 | 50 mA nominal output, ±5% tolerance, same package and AEC-Q100 Grade 3 qualification. | Lowers power dissipation by ~16.7% at same VIN–VLED differential - suitable when lower LED flux or reduced thermal load is acceptable. | Select when system-level current budget allows margin below 60 mA and thermal headroom is constrained. |
| AL5809-90QP1-7 | 90 mA nominal output, ±5% tolerance, identical thermal and voltage specs, AEC-Q100 Grade 3 qualified. | Increases luminous output by 50% but raises power dissipation proportionally - requires upgraded PCB copper and thermal vias. | Choose when higher LED brightness is needed and board-level thermal design supports ≥2.3 W dissipation. |
Compared with AL5809-50QP1-7 and AL5809-90QP1-7, the AL5809-60QP1-7 offers optimal balance between luminous output, thermal management feasibility, and voltage headroom for mid-brightness automotive lighting - avoiding underutilization of drive capability while staying within standard PowerDI123 thermal limits on typical 2-layer FR-4.

FAQ
What is the minimum voltage required to activate the AL5809-60QP1-7?
The device begins conducting after a short delay when voltage across IN and OUT reaches approximately 1.5 V, with full regulation established above 2.5 V. This allows reliable startup even during low-battery conditions (e.g., 9 V cranking), provided the LED forward voltage plus 2.5 V remains within the supply rail.
Can the AL5809-60QP1-7 be used in high-side configuration with common-anode LED strings?
Yes - connect the LED anode to the OUT pin and cathode to the positive supply. The AL5809-60QP1-7 functions identically in high-side mode because it regulates current unidirectionally from IN to OUT, independent of ground reference. No external components are needed for topology change.
Does the AL5809-60QP1-7 support analog dimming or only PWM?
It does not support analog dimming. Brightness control is achieved exclusively via PWM applied to the OUT pin using an external MOSFET switch. Recommended frequency is 100–200 Hz with 5–95% duty cycle; minimum on/off pulse widths are each 500 µs to ensure stable regulation.
How does thermal shutdown behave during sustained overload?
When junction temperature reaches +165°C, the device shuts down current flow and remains off until temperature drops by ≥30°C (hysteresis), then automatically resumes regulation. This protects against irreversible damage during sustained overvoltage or excessive ambient temperature without requiring external reset circuitry.
