Overview
The AL5814MP-13 is a linear LED driver IC from Diodes Incorporated, designed for constant current regulation in lighting applications. It operates within an input voltage range of 4.5 V to 60 V and delivers a fixed output current of 15 mA through a single channel. The device supports PWM dimming functionality and functions at a switching frequency of 50 kHz. It is housed in an MSOP-8 package with exposed pad and is rated for operation between -40 °C and +105 °C.
Feature Summary
- Integrates a precision 1.25V bandgap reference and transconductance amplifier for accurate current control
- Supports external PWM dimming signals for brightness adjustment
- Utilizes a single external resistor to set the output current level
Applications
- Low-power LED indicator circuits
- LED backlighting drivers
- General-purpose constant current LED regulation
Procurement Notes
Verify the specific suffix '13' corresponds to the required tape and reel packaging configuration as defined by the manufacturer. Confirm that the MSOP-8EP package thermal requirements align with the target PCB layout. Ensure compatibility with the 4.5 V to 60 V supply range before finalizing procurement specifications.
Selection Notes
Select this component when a simple linear topology is preferred over switching converters for low-noise applications. It is suitable for designs requiring a single-channel output with fixed 15 mA current. Consider the thermal dissipation capabilities of the MSOP-8 package relative to the voltage drop across the device during operation.
Part Context
This part belongs to the AL58xx series of linear LED controllers manufactured by Diodes Incorporated. These devices are engineered for cost-effective and compact LED driving solutions. The series typically offers various current options and package types to accommodate different power and space constraints in consumer electronics.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family that offer different current ratings or package styles. Verify electrical parameter equivalence, specifically input voltage limits and operating temperature ranges, before substituting.
