AL5814  
60V LINEAR DIMMABLE LED CONTROLLER  
Description  
Pin Assignments  
The AL5814 is an 8-terminal adjustable linear LED driver-controller  
offering excellent temperature stability and output current capability. It  
works with a wide input voltage range from 4.5V to 60V. With an  
external LED driving power device, its internal power dissipation is  
minimized compared with traditional linear LED drivers. This makes it  
ideal for medium to high current LED circuits.

VFAULT  
OUT  
The AL5814 has internal output drive capability up to 15mA, which  
enables it to drive external Bipolar transistors or MOSFETs. It also  
provides the capability to drive longer LED chains with low drop-out  
voltage and multiple LED channels.  
EP  
VSET  
GND  
SFAULT  
FB  
VSET pin is used to directly set output current feedback level. Using a  
resistor divider between REF pin and VSET pin, the output current  
can be set. Additionally, the use of an NTC resistor allows the  
creation of an accurate and configurable thermal fold-back behavior.

MSOP-8EP  
The AL5814 provides an LED-open detection feature through its  
VFAULT pin. If VFAULT is brought lower than 2.5V (by any one of the  
multiple LED channels going open) the AL5814’s output will go low  
turning off the external transistors. The device will recover when the  
open condition is removed. This ability of VFAULT to turn off the  
external transistors also allows PWM dimming of the LED current by  
adding PWM control signal on VFAULT pin.  
Applications  
Automotive Rear Combination Light  
LED Signs  
The AL5814 uses application of power to enable the LED strings. If a  
separate enable pin is needed the AL5817 should be used.  
Instrumentation Illumination  
Refrigerator Lights  
The AL5814 is available in the thermally enhanced MSOP-8EP  
package.  
Features  
Wide Input Voltage Range from 4.5V to 60V  
Configurable LED Current Setting  
4% Reference Voltage Tolerance  
Low Temperature Drift  
15mA Output Drive Capability for MOSFET or Bipolar Transistor  
LED Open Protection Detected by VFAULT Pin  
LED Thermal Fold-back Configured by VSET  
Over Temperature Protection (OTP)  
Input Under Voltage Lock-Out  
PWM Dimming Realized Through VFAULT pin  
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  
Halogen and Antimony Free. “Green” Device (Note 3)  
Notes:  
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.  
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"  
and Lead-free.  
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine  
(<1500ppm total Br + Cl) and <1000ppm antimony compounds.
