LC75843UGA中文资料LCD Driver, 1/1 to 1/4 Duty, General-Purpose数据手册ONSEMI规格书

描述 Description

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.

特性 Features

• 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 segmentsWhen 1/2-duty : Capable of driving up to 54 segmentsWhen 1/3-duty : Capable of driving up to 78 segmentsWhen 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)
• Support for the PWM output function of a maximum of 3ch. (It can output from the general-purpose output port)
• Support for clock output function of 1ch. (It can output from the general-purpose output port)
• Serial data control of the frame frequency of the common and segment output waveforms.
• Serial data control of switching between the internal oscillator operating mode and external clock operating mode.
• High generality, since display data is displayed directly without the intervention of a decoder circuit.
• Built-in LCD drive bias voltage stabilization circuit.
• The INH pin allows the display to be forced to the off state.
• Incorporation of an oscillator circuit. (Incorporation of resistor and capacitor for an oscillation)
• Wide range of operating temperature: -40 to +105°C
• AEC-Q100 qualified and PPAP capable.

应用 Application

• LCD panel for car and home general-purpose display
• Instrument Cluster
• Car air conditioner (HVAC)
• Car audio
• Industrial instruments
• Wattmeter
