AL5814MP-13/AL5817MP-13 LED Linear Configurable Dr

Diodes' AL5814MP-13 and AL5817MP-13 are dimmable and adjustable linear LED driver-controllers. They offer excellent temperature stability with 4% reference voltage tolerance over a wide input voltage range from 4.5 V to 60 V. The AL5817 has an enable bar pin ENB available to disable the device and external transistor drive. The AL5814 has an SFAULT pin allowed to set VCC enable level for LED-open protection. The AL5814MP-13 and AL5817MP-13 can drive external bipolar transistors or MOSFETs. An LED-open detection feature through its VFAULT pin, which turn off the external transistors, also allows PWM dimming signal applied on VFAULT. It is available in the thermally enhanced MSOP-8EP package.

Features
  • Drive external BJT or MOSFET with maximum driving current up to 15 mA
    • Supports high current and high power Linear LED applications
  • Input voltage range from 4.5 V to 60 V
    • Supports wide input voltage range
  • VCC enable level setting for LED-open protection activation (AL5814)
    • Flexible to activate the LED-open detection at certain input voltage

Applications

  • Appliances LED lighting 
  • Instrumentation illumination 
  • Connected lighting
  • Can be dimmed by external analog and PWM signal on VFAULT
    • Flexible when using the dimming functions
  • Robust protections of output open protection, input undervoltage lock-out, and overtemperature protection.
    • Reliable system performance
  • Configurable LED current setting
    • LED current can be configured by NTC and resistor divider between REF and VSET pin
