Monitoring current in power switch devices |
摘要 |
In one example, a method includes generating, by a main switching element of a device, a load current; generating, by a regulation loop of the device, a sense current proportional to the load current; directly converting, by an analog-to-digital converter (ADC) of the device, the sense current into a digital sense current value; and outputting, by the device and to an external device, a digital representation of the load current based on the digital sense current value. |

1. A method comprising:
generating, by a main switching element of a device, a load current; generating, by a regulation loop of the device, a sense current proportional to the load current; directly converting, by an analog-to-digital converter (ADC) of the device, the sense current into a digital sense current value, wherein the regulation loop comprises a chopper amplifier and is operated in synchronization with the ADC; and outputting by the device, to an external device, a digital representation of the load current based on the digital sense current value. |
