Driver chip and driving method of a half bridge circuit

A driver chip of a half bridge circuit for controlling switching of a high side transistor and a low side transistor, comprising:

• a high side input terminal receiving a high side input signal;
• a pulse generator electrically connected to the high side input terminal and transferring a rising edge and a falling edge of the high side input signal into a rise pulse signal and a fall pulse signal, respectively;
• a level shift
• a current supply circuit electrically coupled between the pulse generator and the level shift, and comprising:
• a first switch and a second switch, wherein the rise pulse signal controls the first switch to be switched on such that a first current flows through the level shift, and the fall pulse signal controls the second switch to be switched on such that a second current flows through the level shift, and a current value of the first current is different from that of the second current;
• a current detector electrically connected to the level shift and detecting the first current and the second current for generating a rise current signal and a fall current signal respectively;
• a high side output controller electrically connected the current detector and generating a high side output signal according to the rise current signal and the fall current signal;
• and
• a high side output terminal, electrically connected to the high side output controller and the high side transistor and outputting the high side output signal to control the switching of the high side transistor.
