The SPOC - BTS5682E is supplied by two supply voltages
switches. The
pins VDD and GND is recommended as shown in
There is a power-on reset function implemented for the V
supply, all SPI registers are reset to their default values. The SPI interface including daisy chain function is active
as soon as
contains at pin SO the read information from register OUT, the transmission error bit TER is set.

Diagnosis
1) SPI read only.
2) Depending on latched channel 5.
3) When DCR.MUX = 111
4) When all channels are in OFF-state and DCR.MUX!= 111
5) Current sense disabled in limp home mode.
Stand-by mode is entered as soon as the current sense multiplexer (DCR.MUX) is in default (stand-by) position
and channel 5 is not latched in ON-state
stand-by mode is entered, register HWCR.STB is set. The state of channel 5 can be read via HWCR.CH5. To wake-
up the device, the current sense multiplexer (DCR.MUX) is programmed different to default (stand-by) position.
Idle mode parameters are valid, when all channels are switched off, but the current sense multiplexer is not in
default position, and
Limp home (LHI = high) will wake-up the device and is working without
be activated via the dedicated input pins. The cranking latch is not available in limp home mode in order to switch
to stand-by mode after limp home.
