Abstract:
A bridge output circuit includes an output terminal, a high side transistor, a low side transistor, a high side driver for controlling a gate voltage of the high side transistor, a low side driver for controlling a gate voltage of the low side transistor, and a controller for controlling the high side and low side drivers. The low side driver includes a first current source, a second current source, and a first assist circuit. The controller is configured to control the turning-on and turning-off states of the first current source, the second current source and the first assist circuit.
