Abstract
A bootstrap diode circuit includes an anode for coupling to a power supply voltage terminal and a cathode for coupling to a bootstrap voltage terminal. The bootstrap diode circuit also includes a high-voltage p-type metal-oxide-semiconductor (PMOS) transistor, having a source forming the cathode of the bootstrap diode circuit and a drain forming the anode of the bootstrap diode circuit. The high-voltage PMOS transistor has a breakdown voltage higher in magnitude than a voltage drop between a maximum bootstrap voltage and the power supply voltage.
