OVER-CURRENT DETECTION FOR BUS LINE DRIVERS |
| 摘要 |
An electrical circuit for driving a bus is described that includes at least one branch coupled to at least one signal line at a termination of the bus and a transmit data input configured to receive data that the electrical circuit drives across the bus. The electrical circuit also includes a current detection unit coupled to the at least one branch, which is configured to detect a current through the at least one branch. The electrical circuit also includes an over-current determination unit coupled to both the current detection unit and the transmit data input. The over-current determination unit is configured to determine an over-current condition at the at least one branch based on the current at the at least one branch and the data at the transmit data input. |

1. An electrical circuit for driving a bus, comprising:
at least one branch coupled to at least one signal line at a termination of the bus; a transmit data input configured to receive data that the electrical circuit drives across the bus; a current detection unit coupled to the at least one branch, wherein the current detection unit is configured to detect a current through the at least one branch; and an over-current determination unit coupled to both the current detection unit and the transmit data input, wherein the over-current determination unit is configured to determine an over-current condition at the at least one branch based on the current at the at least one branch and the data at the transmit data input. |
