Abstract
Sensing current flowing through a semiconductor device includes providing an input pin to receive an input, providing an output pin coupled to a predefined voltage source, providing a control pin to receive a control signal for controlling a flow of current between the output pin and the input pin, and electrically coupling a Kelvin sense pin to an output pad located on a semiconductor die of the device. An electrical path from the output pad to the output pin has a predefined resistance. The current is Kelvin current sensed using the predefined resistance. A flow of an output current provided to a load coupled to the device is interrupted when a value of the current is greater than a predefined value.
Claims6
A method for sensing current flowing through a semiconductor device, the method comprising:
- providing an input pin to receive an input;
- providing an output pin coupled to a predefined voltage source;
- providing a control pin to receive a control signal for controlling a flow of current between the output pin and the input pin;
