Product Description

MBI1816 is an instant On/Off LED driver for lighting applications and exploits PrecisionDrive™ technology to enhance

its output characteristics. At MBI1816 output stage, sixteen regulated current ports are designed to provide uniform and

constant current sinks for driving LEDs within a large range of V_Fvariations.

MBI1816 provides users 16-channel constant current ports to match LEDs with equal current. Users may adjust the

output current from 5 mA to 90 mA through an external resistor, R_ext, which gives users flexibility in controlling the light

intensity of LEDs. In addition, users can adjust device brightness via OE pin. The duty cycle of OE can decide the

brightness intensity from 0% to 100%. MBI1816 guarantees to endure maximum 17V at the output ports.

Additionally, to ensure the system reliability, MBI1816 is provided in the TSSOP20 with thermal pad for dramatically

increased power dissipation capability. As a result, a large amount of current can be handled safely in one package.
