DRIVER WITH VARIABLE OUTPUT VOLTAGE AND CURRENT |
摘要 |
A driver circuit with variable output voltage and current. A source input terminal of the driver circuit may receive a source control signal. A voltage control circuit may drive one of the terminals of a first switch to a source voltage. If the source input terminal receives an asserted source control signal, the first switch is turned on and the voltage control circuit drives an output terminal of the driver circuit to the source voltage. A source current mirror may regulate a source current provided to the output terminal of the driver circuit. A sink input terminal of the driver circuit may receive a sink control signal. If the sink input terminal receives an asserted sink control signal, a second switch is turned on and the output terminal is driven to a sink voltage. A sink current mirror may regulate a sink current provided to output terminal of the driver circuit.
