1.1.5 Power Stage OUT8
This circuit is available in MQFP64 package or as chip.
*) only serial control possible (via SPI)
Parallel connection of power stages is possible (see 1.13)
Internal short-circuit protection
Phase relation: non-inverting (exception: IN8->OUT8 is inverting)
The following types of error can be detected:
Individual detection for each output.
Serial transmission of the error code via SPI.
Low signal at pin ABE and shut-off of the power stages if VDD is out of the permitted range.
Exception: If OUT8 is controlled by IN8, OUT8 will only be switched off by the overvoltage
detection and not by undervoltage detection.
The state of VDD can be read out via SPI.
Alternatively to the parallel and SPI control of the power stages, a high speed serial bus inter-
face can be configured as control of the power stages OUT1...OUT7 and OUT9...OUT16.
OUT8 can be controlled by SPI or by the pin IN8 only. When controlled by IN8 this power stage
is functional if the voltage at the pin VDD is above 3,5V.
SPI mode the power stage is fully supervised by the VDD-monitor.
