Abstract:
A driver system operable to supply a drive signal to a motor includes a system input adapted to be coupled to an input voltage and a system output adapted to be coupled to the motor. The driver system includes a high-side transistor which has a first terminal coupled to the system input, a second terminal coupled to the system output, and has a control terminal. The driver system includes a low-side transistor which has a first terminal coupled to the system output, a second terminal coupled to a reference potential terminal, and has a control terminal. The driver system includes a low-side gate control circuit which provides a first level current responsive to a low-side digital control signal transitioning from a low state to a high state and provides a second level current if the output voltage is less than an upper reference voltage.
