MISO

Back supply current into supply pin of MISO is not allowed.

Back to Back structure: in case of an over-voltage condition at the MISO output, the HS path

(Back to Back) has to be switched off after tOFF_PROT by analog circuitry to avoid back

supply current into supply pin of SDO.

Protection of SDO Output

The internal LS driver must withstand a direct short circuit to battery (current limitation or

shutdown possible, no destruction allowed).

The internal HS driver must withstand a direct short circuit to GND (current limitation or

shutdown possible, no destruction allowed).
