The BD8163EFV is a system power supply IC for TFT panels. A 1-chip IC providing a total of four voltages required for TFT panels, i.e., logic voltage, sauce voltage, gate high-level, and gate low-level voltage, thus constructing a TFT panel power supply with minimal components required.

The BD81842MUV-M is a power management IC for TFT-LCD panels which are used in car navigation, in-vehicle center panel, and instrument cluster. Incorporates high-power FET with low on resistance for large currents that employ high-power packages, thus driving large current loads while suppressing the generation of heat. A charge pump controller is incorporated as well, thus greatly reducing the number of application components. Also Gate Shading Function is included.

BD81870EFV is current mode step-up and inverted 2-channel switching regulator with built in FET.

BD81A24MUV-M / BD81A24EFV-M (HTSSOP-B28 package) is a white LED driver with the capability of withstanding high input voltage (35V Max). This driver has 4ch constant-current drivers integrated in 1-chip, where each channel can draw up to 120mA (Max), which is also suitable for high illumination LED drive. Furthermore, a buck-boost current mode DC/DC controller is also integrated to achieve stable operation during power voltage fluctuation. Light modulation (10,000:1 @100Hz dimming function) is possible by PWM input.

BD81A74MUV-M / BD81A74EFV-M (HTSSOP-B28 package) is a white LED driver with the capability of withstanding high input voltage (maximum 35V). This driver has 4ch constant-current drivers in 1-chip, where each channel can draw up to 120mA (Max), and it is suitable for high illumination LED drive. Furthermore, a buck-boost current mode DC/DC controller is also built to achieve stable operation during power voltage fluctuation. Light modulation (10,000:1@100Hz dimming function) is possible by PWM input.

This is the product guarantees long time support in Industrial market. Single channel high side switch IC for USB port is a high side switch having over current protection used in power supply line of universal serial bus (USB). N-channel power MOSFET of low on resistance and low supply current are realized in this , over current detection circuit, thermal shutdown circuit, under voltage lockout and soft start circuit are built in.
