onsemi LC75890W
The LC75890W is the 1/4 duty and static drive general-purpose LCD display driver that can be used for displaying segments for household appliances, home audio visual products, portable devices and other such products under the control of a microcontroller.The LC75890W can drive up to 148 segments directly. They can control the brightness of the LED backlight of RGB, because they have the PWM output of greatest 3CH built-in. In addition the LC75890W can control up to 12 general-purpose output ports.| Part No. | LC75890W |
