Abstract
In an example embodiment, a universal serial bus (USB) Type-C controller comprises a current detector circuit configured to provide over-current protection on a voltage bus (VBUS) line. The current detector circuit comprises a current sense amplifier, a reference voltage generator, and a comparator coupled to the current sense amplifier and to the reference voltage generator. The current sense amplifier is configured to receive a pair of input voltages from the VBUS line and to output an indicator signal responsive to an input voltage difference between the pair of input voltages. The reference voltage generator is configured to generate a reference voltage in response to a voltage selector signal. The comparator is configured to output an interrupt signal responsive to the indicator signal exceeding the reference voltage.
