MAX16814BEUP+

The MAX16814BEUP+ is a integrated, 4-channel, high brightness LED driver with high voltage DC-DC controller in 20 pin TSSOP package. It consists of 4 identical linear current source channels to drive 4 strings of HB LEDs. The channel current is adjustable from 20mA to 150mA with an accuracy of ±3% using an external resistor. External resistor sets all 4-channel currents to same value. Device allows connecting multiple channels in parallel to achieve higher current per LED string. It features pulsed dimming control on all four channels through a logic input (DIM), a unique feature that allows a very short minimum pulse width as low as 1µs. It includes output overvoltage, openLED detection and protection, programmable shorted LED detection and protection and overtemperature protection. It is used in automotive displays LED backlights, automotive RCL, DRL, front position and fog lights, LCD TV and desktop display LED backlights, architectural, industrial and ambient lighting.
