Product Description
MBI5907 is a specific power switch for scan type LED display. It has two output channels, operate from 5V to 3.3V,
supports 2A maximum output current per channel.
Moreover, there are internal circuits to eliminate common problems happened in scan type LED display. Such as
upper ghosting 、high contrast interference* and color stripe which is caused by shorted LED.
*Function of eliminating high contrast interference requires MBI constant current drivers equipped with grayscale
data compensation technology.
Application
LED display

Operation Principles
MBI5907 is a dual channel power switch specified for scan type LED display. It integrates two P-MOSFET、gate
driver and discharge control circuit. Each P-MOSFET provides 2A maximum current with 100m ohm ON resistance
(RDS(ON)).
When EN is” LOW”, P-MOS will turn on. While EN is “HIGH”, P-MOS will turn off. Then discharge control circuit will
activate. Discharge circuit will eliminate upper ghosting 、high contrast interference and color stripe of scan type
LED display.
