5.1
The TLE7233G offers the capability of driving dedicated channels during eventual fail-safe operation of the
system. This limp home mode is activated by a high signal at pin LHI. In this mode, the SPI registers are reset and
the input pins are directly routed to their corresponding channels, see
Furthermore, the SPI is ignored and all input pin are referred to
if the digital supply or the microcontroller fail.
A high signal on LHI overrides a Reset signal on RST. In case of a limp home during sleep the device will therefore
wake up and enter the limp home mode.
During Limp home mode any SPI transmission will receive a TER flag.
After limp home operation all registers are reset and the device enters in sleep mode following low logic RST state,
or returns to ON state (all channels OFF with diagnostic currents active). Next SPI transmission will receive a TER
Flag.
