LC75805PEH-3H

LCD 驱动器 LED AND LCD DISPLAY DRIVE

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.
