LC75805PEH-3H is the 1/1 to 1/4 duty general-purpose LCD display driver with the LED driver to use for the instrument panel display by control with the controller. In addition, LC75805PEH-3H is able to drive up to 48 LED and LCD of up to 140 segments directly, and has a built-in 7ch PWM function for brightness adjustment of LED. Furthermore, because of built-in the oscillator circuit, it is possible to reduce external resister and capacitor for oscillation.
Feature
- Switch of Static Drive, 1/2 Duty Drive, 1/3 Duty Drive and 1/4 Duty Drive can be controlled by serial data.Static Drive (1/1 Duty Drive) : Capable of driving up to 38 segments.1/2 Duty Drive : Capable of driving up to 74 segments.1/3 Duty Drive : Capable of driving up to 108 segments.1/4 Duty Drive : Capable of driving up to 140 segments.
- Frame frequency of common and segment output waveform can be controlled by serial data.
- Turning on/off LED can be controlled by serial data. (Capable of driving up to 48 LED)
- Built-in 7ch PWM function for brightness adjustment of LED. (Resolution of 128 steps)
- Frame frequency of LED driver output waveform can be controlled by serial data.
- Serial data input supports 'computer control bus' format communication with the system controller. (Support 5 V operation)
- Backup function and forced turning off all segments by power-saving mode can be controlled by serial data.
- Switch of the internal oscillator operating mode and the external clock operating mode can be controlled by serial data.
- High generality, since display data is displayed directly without the intervention of a decoder circuit.
- The INH pin allows the display to be forced to the off state.
- Built-in Oscillator circuit (Built-in resister and capacitor for oscillation)
- Operating temperature: -40 to +95°C
Applications
- LCD panel for car and home general-purpose display
