LC75805PE

Ordering number : ENA2119A LC75805PE CMOS IC 1/1 to 1/4 Duty General-Purpose LCD Display Driver with LED Driver http://onsemi.com Overview LC75805PE 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, LC75805PE 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. Features  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 CCB format communication with the system controller. (Support 5V operation)  Backup function and forced turning off all segments by power-saving mode can ...
