MBI is an instant On/Off LED driver for LED backlight applications and exploits PrecisionDrive? technology to enhance its output characteristics. At MBI output stage, regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of VF variations, and in order to eliminate the heat generated by VF variations, a feedback function is integrated in MBI to control the LED power source.
MBI provides -channel constant current ports to match LEDs with equal current. Users may adjust the output current from mA to mA 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 % to % via output enable pin (OE) with pulse width modulation signal.
MBI can detect the error status of LED open-circuit, short-circuit, and the over temperature during the operation, and the pins, /ERR and /TH report these fault conditions. When LED open-circuit or short-circuit faults happen, only the faulted channel will be shut down to avoid affecting other normal channels. MBI will disable all the output channels until the junction temperature is lower than the hysteresis, if the over temperature status occurs.
Additionally, to ensure the system reliability, MBI is built with thermal pad which enhances the heat dissipation.
