Final Data Sheet
Reading the IC Identifier (SPI Instruction: RD_IDENT1):
Reading the IC revision number (SPI Instruction: RD_IDENT2):
Reset of the Diagnostic Information (SPI Instruction: DEL_DIA):
Resets the 5 diagnostic registers DIA_REG1...5 to FFH and the common overtemperature flag in regis-
ter STATCON_REG (Bit4) to High. These bits are only cleared by the DEL_DIA instruction when there
is no failure entry at the input of the registers.
Access is performed like a writing access with any data byte.
In the case a power stage is shut off because of SCB, the output is activated again by the DEL_DIA
instruction and the filtering-time is enabled. Therefore in case of SCB the output is activated and shut
off after the shutoff delay.
For a power stage in the current limitation mode, the current limitation mode is left, if a DEL_DIA
instruction has been received. If there is still the condition for SCB the current limitation mode
is entered again.
On the following pages the conditions for set and reset of the SCB report in DIA_REGx is shown in
several schematics. The signal „power stage control“ is generated as follows:
