ABE/DIS DIA21 DIA20 DIA11 DIA10 Description
Note:
The bit ABE/DIS shows directly the status of inputs ABE and DIS. It is set to ‘0’ if the power stages are disabled
by ABE or DIS.
The bits OT, CurrRed and CurrLim are latched. They will be reset with each read access. If the failure condition is
still present the according bits are set again.
Undervoltage at VS is reported and the outputs are switched off as long as the undervoltage condition is present.
The previous setting of the DIAx bits is masked but not reset. Once the supply voltage is back in the operating
range the diagnostic bits DIAxx will return to their setting before VS undervoltage. The outputs will return to normal
operation.
Detection of short circuit will switch of the output stages. In single half bridge operation only the affected output is
switched off. In H-Bridge mode both outputs are shut down. The outputs remain off until the failure condition is
removed and the diagnosis register is reset.
A short across the load may also be reported as SCG at one output and SCB at the other.
The diagnostic information DIAxx in the SPI interface is reset in the following cases:
