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 VF variations. MBI1816 provides users 16-channel constant current ports to match LEDs with equal current. Users may adjust the output current from 5 m A to 60 m A through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. In addition, users can precisely adjust LED brightness from 0% to 100% via output enable ( OE ) with Pulse Width Modulation. Additionally, to ensure the system reliability, MBI1816 is built with Thermal Protection (TP) function and thermal pad. The TP function protects IC from over temperature (165°C). Also, the thermal pad enhances the power dissipation. As a result, a large amount of current can be handled safely in one package.
