PROGRAMMABLE POWER DISTRIBUTION SWITCHES WITH TWO-LEVEL CURRENT SENSING |
摘要 |
Programmable power distribution switches with two-level current sensing are disclosed. In a particular example, a power distribution switch includes a programmable output device having a resistance based on a programmed maximum output current and generates an output voltage based on the resistance and a load current. The example power distribution switch also includes a reference voltage generator that is configured to generate a reference voltage corresponding to the output voltage when the load current is substantially equal to the programmed maximum output current. A current limiter is also included to reduce the load current in response to a comparison of the output voltage and the reference voltage, when the comparison is indicative of the load current exceeding the programmed maximum output current.
