Product details
Overview
AL5809-60P1-7 from Diodes Incorporated is a two-terminal linear constant current LED driver in PowerDI123 package, delivering 60 mA ±5% regulated current over -40°C to +125°C with 2.5 V to 60 V input-output voltage range and 20 ppm/°C temperature drift. It supports both high-side and low-side LED string configurations for offline AC/DC LED lamps and signage.
For engineers reviewing the AL5809-60P1-7 datasheet, AL5809-60P1-7 pinout, AL5809-60P1-7 application, or AL5809-60P1-7 equivalent, key selection criteria include its floating-ground 60 V rating, thermal shutdown at +165°C, PWM dimming compatibility down to 100 Hz, and absence of external current-setting resistors.
Technical Context
The AL5809-60P1-7 integrates an internal precision current mirror and low-dropout regulator to maintain stable 60 mA output across 2.5–60 V differential input, with line regulation ≤1% and startup threshold at 1.5 V minimum. Its thermal shutdown activates at +165°C junction temperature with +30°C hysteresis.
It operates as a two-terminal series regulator-no ground reference required-enabling direct insertion into LED strings regardless of topology. The device draws power from the IN–OUT voltage drop and regulates current via internal fixed-resistor reference, eliminating external components while maintaining ±5% accuracy over full temperature and voltage range.

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 |
|---|---|---|---|
| AL5809-60S1-7 | SOD-123 package, lower power rating (0.36 W), higher θJA (278°C/W) | Limited to lower ambient temperatures (<+60°C) and shorter LED strings due to thermal constraints | Select only when board space is extremely limited and power dissipation remains below 150 mW |
| NSI45060AZT1G | Onsemi 60 mA driver in SOD-123; ±3% accuracy, 100 ppm/°C drift, no thermal shutdown | Lacks overtemperature protection and exhibits greater current drift above 85°C | Prefer for cost-sensitive consumer lighting where thermal margin is guaranteed and long-term stability is secondary |
Compared with AL5809-60P1-7, the AL5809-60S1-7 trades thermal robustness for footprint reduction, while the NSI45060AZT1G offers tighter initial accuracy but sacrifices temperature stability and safety features-making the AL5809-60P1-7 optimal for industrial and outdoor applications demanding reliability across extremes.

FAQ
What is the minimum voltage required to turn on AL5809-60P1-7?
The AL5809-60P1-7 requires a minimum 2.5 V differential between IN and OUT pins to begin regulating current. Below this threshold, the device remains in cutoff and draws negligible current. This allows use in systems where input voltage may dip temporarily without disrupting LED operation.
Can AL5809-60P1-7 be used in high-side configuration with common-anode LED arrays?
Yes-AL5809-60P1-7 supports high-side configuration by connecting the LED anode to the OUT pin and the cathode to the IN pin. Its floating-ground architecture eliminates the need for level-shifting circuitry, enabling direct integration into common-anode topologies without additional components.
How does thermal shutdown behave during continuous overtemperature conditions?
When junction temperature reaches +165°C, AL5809-60P1-7 disables current flow until temperature drops by ≥30°C (to ≤+135°C), then resumes regulation. This hysteresis prevents oscillation and provides safe recovery without external intervention-critical for enclosed LED fixtures with limited airflow.
Is AL5809-60P1-7 suitable for PWM dimming below 100 Hz?
No-datasheet-specified PWM dimming range is 100–200 Hz. At frequencies below 100 Hz, visible flicker occurs due to insufficient duty cycle resolution and slow response relative to human persistence of vision. For sub-100 Hz control, a dedicated dimming IC or analog current adjustment is recommended.
