LED Driver IC 1 Output DC DC Controller SEPIC, Step-Down (Buck), Step-Up (Boost) Analog, PWM Dimming 8-SO-EP # AL8866QSP-13 Engineering Specifications **General Description** The AL8866QSP-13 is an automotive-qualified, multi-topology DC-switching LED controller manufactured by Diodes Incorporated. It is designed to control an external power MOSFET for high-power automotive LED lighting systems. The device supports buck, boost, buck-boost and single-ended primary-inductance converter configurations. Its wide input-voltage range makes it suitable for automotive power systems and various high-voltage LED applications. The controller uses fixed-frequency peak current-mode regulation with spread-spectrum frequency modulation to reduce electromagnetic interference. It supports both analog and pulse-width-modulation dimming through the DIM input. An integrated programmable soft-start function gradually increases the inductor and switching currents during startup to reduce output-voltage and current stress. The open-drain fault output provides system-level fault reporting for abnormal operating conditions. **Engineering Specifications** **Manufacturer:** Diodes Incorporated **Manufacturer Part Number:** AL8866QSP-13 **Component Type:** Automotive LED driver controller **Converter Topologies:** Buck, boost, buck-boost and SEPIC **Control Architecture:** Fixed-frequency peak current-mode control **External Switching Device:** External power MOSFET **Minimum Input Voltage:** Four point seven volts **Maximum Input Voltage:** Eighty-five volts **Maximum Output Voltage:** Eighty-five volts **Switching Frequency:** Four hundred kilohertz **Frequency Modulation:** Spread-spectrum modulation for reduced electromagnetic interference **LED Current Control:** External current-sense resistor and external MOSFET configuration **Feedback Voltage:** Two hundred millivolts **Typical Quiescent Current:** One point eight milliamperes **Typical Efficiency:** Up to approximately ninety-three percent, depending on the application circuit and external components **Dimming Methods:** Analog dimming and pulse-width-modulation dimming **Analog Dimming Range:** One percent to one hundred percent **Analog Dimming Dynamic Range:** Greater than one hundred to one **Pulse-Width-Modulation Dimming Ratio:** One hundred to one at a two-hundred-hertz dimming frequency **Pulse-Width-Modulation Frequency Range:** Approximately one hundred hertz to one kilohertz **Full-Brightness Current Accuracy:** Approximately plus or minus three percent **Low-Level Dimming Current Accuracy:** Approximately plus or minus twelve percent at twenty-percent dimming **Soft-Start Function:** Externally programmable **Fault Output:** Active-low open-drain fault indicator **Protection Features:** Output overvoltage protection, LED open-circuit protection, output undervoltage protection, LED short-circuit protection, cycle-by-cycle overcurrent limitation, current-sense resistor short-circuit protection, inductor and diode short-circuit detection, diode open-circuit protection and thermal shutdown **Automotive Qualification:** AEC-Q100 Grade One qualified **Automotive Documentation:** PPAP capable **Manufacturing Standard:** Manufactured in IATF-certified automotive facilities **Operating Temperature Range:** Minus forty degrees Celsius to positive one hundred twenty-five degrees Celsius **Package Type:** Thermally enhanced SO-8 exposed-pad package **Pin Count:** Eight leads with exposed thermal ground pad **Mounting Style:** Surface mount **Packing Method:** Thirteen-inch tape and reel **Standard Packing Quantity:** Two thousand five hundred components per reel **Moisture Sensitivity:** Level One **Terminal Finish:** Matte-tin-plated leads **Environmental Compliance:** Lead-free, RoHS compliant, halogen-free and antimony-free **Typical Applications** Automotive high-beam and low-beam lighting Automotive daytime running lights Automotive fog lights Automotive turn-signal lights Automotive position lights Automotive brake and stop lights High-power exterior LED lighting Multi-topology automotive LED driver modules #AL8866QSP13 #AL8866Q #DiodesIncorporated #LEDDriver #AutomotiveLED #AutomotiveElectronics #BuckConverter #BoostConverter #BuckBoostConverter #SEPICConverter #PowerElectronics #LEDLighting #ElectronicComponents #EngineeringSpecifications

OR Controller N+1 ORing Controller N-Channel N:1 6-DFN (2x3) The LTC®4359 is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. It controls the forward-voltage drop across the MOSFET to ensure smooth current delivery without oscillation even at light loads. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. A shutdown mode is available to reduce the quiescent current to 9μA for load switch and 14µA for ideal diode applications. When used in high current diode applications, the LTC4359 reduces power consumption, heat dissipation, voltage loss and PC board area. With its wide operating voltage range, the ability to withstand reverse input voltage, and high temperature rating, the LTC4359 satisfies the demanding requirements of both automotive and telecom applications. The LTC4359 also easily ORs power sources in systems with redundant supplies - Reduces Power Dissipation by Replacing a Power Schottky Diode - Wide Operating Voltage Range: 4V to 80V - Reverse Input Protection to – 40V - Low 9µA Shutdown Current - Low 150μA Operating Current - Smooth Switchover without Oscillation - Controls Single or Back-to-Back N-Channel MOSFETs - Available in 6-Pin (2mm × 3mm) DFN, 8-Lead MSOP and 8-Lead SO Packages - AEC-Q100 Qualified for Automotive Applications #CommonPartsLibrary #IntegratedCircuit #PowerManagement #OR-Controller
