4.12
These outputs are two high side drivers, intended to drive small resistive loads or LEDs incorporating the following
features:
4.12.1
Each high side driver signals an open load condition if the current through the high side is below the open load current threshold.
The open load condition is indicated with the bits HS1OL and HS2OL in the High Side Status Register (HSSR).
4.12.2
Each high side driver has an output current limitation. In combination with the over-temperature shutdown the high side drivers
are protected against over-current and short-circuit failures.
That the driver operates in the current limitation area is indicated with the bits HS1CL and HS2CL in the High Side Status Register
(HSSR).
4.12.3
Both high side drivers are protected against over-temperature. In over-temperature conditions, both high side drivers are shut
down and the event is latched in the Interrupt Control Module. The shutdown is indicated as HS Interrupt in the Interrupt Source
Register (ISR).
A thermal shutdown of the high side drivers is indicated by setting the HSOT bit in the High Side Status Register (HSSR).
A write to the High Side Control Register (HSCR), when the over-temperature condition is gone, will re- enable the high side
drivers.
4.12.4
In case of a high voltage condition (HVI), and if the high voltage shutdown is enabled (bit HVSDE in the High Side Control Register
(HSCR) is set), both high side drivers are shut down. A write to the High Side Control Register (HSCR), when the high voltage
condition is gone, will re-enable the high side drivers.
4.12.5
The high side drivers can be enabled to operate in Sleep and Stop mode for cyclic sensing. See
