Abstract
The system comprises a plurality of driver modules coupled by a fault condition bus, e.g. single-wire bus. Each driver module includes an Error Flag Interface block coupled between a single terminal error flag input/output (EF I/O) and a Control block. Each driver module may be coupled- to a motor. When a driver module detects a local fault condition, its Error Flag Interface block is configured to lower the voltage at the single terminal EF I/O to communicate the change to the other driver modules. The Error Flag Interface block is further configured to monitor voltage changes at its single terminal EF I/O. An external fault condition is detected when the single terminal EF I/O is at a low voltage. The Error Flag Interface block is further configured to send a signal disabling the output of the driver module.
