Abstract
A driver integrated circuit includes a bootstrap circuit (BSC) configured to output a boot power supply voltage (VB) based on a first power supply voltage, the boot power supply voltage being higher than the first power supply voltage; a level shift circuit (LSC) configured to output an output pulse signal based on an input pulse signal and the boot power supply voltage; a high side driving circuit (HSU) configured to output a high side driving voltage based on the boot power supply voltage and the output pulse signal, wherein the bootstrap circuit includes a sense metal oxide semiconductor (MOS) transistor and a boot MOS transistor, wherein the sense MOS transistor includes a depression-type transistor.
