M62295GP

MITSUBISHI(Standard Linear ICs) M62295GP M62295GP LCDPC BACK-LIGHT IC BACK- LIGHTCONTROL CONTROL IC DESCRIPTION M62295GP is a semiconductor integrated circuit designed for PC back- light control, which employs 2 output totempole output circuit specifically suitable for inverter drive with piezo device. Such necessary functions as light control, protection circuit are housed in 16pin SSOP package. This allows for simplified peripheral circuit as well as compact and thin set design.
