Product Description
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.
Applications
High-flux LED lighting
Automotive interior lighting
