The LC75843UGA is the 1/1 to 1/4 duty general-purpose microprocessor-controlled LCD driver that can be used in applications such as Automotive display. In addition to being able to drive up to 100 segments directly, the LC75843UGA can also control up to 4 general-purpose output ports. Because it has the PWM output of a maximum of 3ch, the brightness control of the LED backlight of RGB can be done. Incorporation of an oscillation circuit helps to reduce the number of external resistors and capacitors required.
-
Support for static(1/1duty) or 1/2-duty 1/2-bias or 1/3-duty 1/3-bias or 1/4-duty 1/3-bias drive techniques under serial data control.
- When 1/1-duty : Capable of driving up to 28 segments
- When 1/2-duty : Capable of driving up to 54 segments
- When 1/3-duty : Capable of driving up to 78 segments
- When 1/4-duty : Capable of driving up to 100 segments
-
Serial data input supports 'computer control bus' format communication with the system controller. (Support 3.3 V and 5 V operation)
-
Serial data control of the power-saving mode based backup function and the all segments forced off function.
-
Serial data control of switching between the segment output port and general-purpose output port function. (Support for up to 4 general-purpose output ports)
