MBI1802 is an instant On/Off LED driver for high power LED applications and exploits PrecisionDrive™ and All-Ways-On™ technology to enhance its output characteristics.
With All-Ways-On™, MBI1802 provides users with 2-channel constant current ports. Users may adjust the output current up to 360 mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. Also, users can precisely adjust LED brightness from 0% to 100% via output control with Pulse Width Modulation. Alternatively, MBI1802 provides one-step current adjustment to make 25% of the output current via enabling the quarter pin (/QT) as “Low”.
Additionally, to ensure the system reliability, MBI1802 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 sunk safely in one package..
