SHUTDOWN PROTECTION FOR BUS LINE DRIVERS |
| 摘要 |
An electrical circuit for driving a bus is described that includes a plurality of branches 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 an over-current validation unit coupled to the transmit data input which is configured to validate an over-current condition detected at a first branch of the plurality of branches based at least in part on the data at the transmit data input. The electrical circuit also includes a branch control unit coupled to the over-current validation unit which is configured to disable at least one of the plurality of branches in response to a validated over-current condition at the first branch. |

1. An electrical circuit for driving a bus, comprising:
a plurality of branches 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; an over-current validation unit coupled to the transmit data input, wherein the over-current validation unit is configured to validate an over-current condition detected at a first branch of the plurality of branches based at least in part on the data at the transmit data input; and a branch control unit coupled to the over-current validation unit and configured to disable at least one of the plurality of branches in response to a validated over-current condition at the first branch. |
