Apparatus to charge bootstrap capacitor

Abstract

In some aspects, an integrated circuit comprises an input voltage terminal, a capacitor terminal, a first NMOS transistor connected to the input voltage terminal, a first PMOS transistor connected to a first NMOS gate terminal of the first NMOS transistor and connected to the capacitor terminal, the first PMOS transistor having a first PMOS gate terminal, a second PMOS transistor connected to the first NMOS gate terminal of the first NMOS transistor, the second PMOS transistor having a second PMOS gate terminal, a switched output terminal, a second NMOS transistor connected to the switched output terminal, a third NMOS transistor connected to the switched output terminal, an inverter, and a complementary metal oxide semiconductor (CMOS) transistor pair, the CMOS transistor pair having an input connected to the third NMOS transistor and an output connected to a second PMOS gate terminal of the second PMOS transistor.
