8.2
Functional Description
The High-Side switches can be used for control of LEDs, as supply for the wake inputs and for other loads. The
High-Side outputs can be controlled either directly via SPI by (HS_CTRL1, HS_CTRL2), by the integrated timers
or by the integrated PWM generators.
The high-side outputs are supplied by a dedicated supply pin VSHS (different to VS). The topology supports
improved cranking condition behavior.
The configuration of the High-Side (Permanent On, PWM, cyclic sense, etc.) drivers must be done in SBC Normal
Mode. The configuration is taken over in SBC Stop- or SBC Sleep Mode and cannot be modified. When entering
SBC Restart Mode or SBC Fail-Safe Mode the HSx outputs are disabled.
