MAXIM INTEGRATED / ANALOG DEVICES MAX16814AUP High-Brightness LED Driver
The MAX16814AUP+ is an integrated 4-channel high-brightness LED driver with a high-voltage DC-DC controller, housed in a 20-pin TSSOP package. It features four identical linear current source channels to power up to four strings of high-brightness LEDs, with adjustable current from 20mA to 150mA and a typical accuracy of ±3% via an external resistor. Connecting multiple channels in parallel allows for higher current per LED string. The device supports pulsed dimming on all channels through a logic input (DIM), capable of pulse widths as short as 1 microsecond. It includes various protections such as overvoltage, open-LED detection, programmable shorted LED protection, and overtemperature shutdown. Operating over a voltage range of 4.75V to 40V and an automotive temperature range from -40°C to 125°C, it is ideal for automotive displays, LED backlighting in LCD TVs and desktops, architectural, industrial, and ambient lighting applications. The device integrates internal MOSFETs for each channel, supports multiple LED topologies like boost, boost-buck, or SEPIC via a supporting DC-DC controller, and offers programmable switching frequencies for size and efficiency optimization. Additional features include PWM dimming at 200Hz with low shutdown current, external frequency synchronization, fault indicators, and protection against shorts and overheating.
