The SPOC - BTS5590G is supplied by two supply voltages
switches and by an internal power supply for the limp home function. The limp home power supply is enabled by
pin LHEN. As a result, the stand-by current is minimized only when limp home function is disabled. The
line is used by the SPI related circuitry and for driving the SO line. A capacitor between pins VDD and GND is
recommended.
There is a power-on reset function implemented for the
supply, all SPI registers are reset to their default values. The SPI interface including daisy chain function is active
as soon as

Diagnosis
1) An active and unserved watchdog will cause limp home mode after overrun.
2) SPI reset in limp home mode.
3) When all channels are in OFF-state and all SPI registers are at default values.
4) Current sense diagnosis not available in limp home mode.
To achieve stand-by mode, the limp home block must be disabled (LHEN = 0 V), all channels must be switched
off and the thermal latches have to be cleared. As a result the stand-by current I
