  • Integrated gate driver for motor control
    Patent number: 9954422
    Abstract: An integrated gate driver for motor control includes a first diode coupled to an upper rail and providing a voltage on a first connector and a power amplifier coupled between the first connector and a second connector that can be coupled to a source of a high-side power transistor. The power amplifier receives a control signal and provides an output signal to a second pin for driving a gate of the high-side power transistor. A first integrated capacitor is coupled between the first and second connector and an integrated charge pump is coupled to supply a current to the first connector. The charge pump includes a second integrated capacitor having a terminal coupled to a high frequency oscillator and a terminal coupled through a second diode to the first connector and a third diode coupled between the second connector and a point between the second capacitor and the second diode.
