OTF: thermal protection and diagnostic

The LNBH30 is also protected against overheating: when the junction temperature exceeds

150 °C (typ.), the step-up converter and the liner regulators are shut off, the diagnostic OTF

bit in the status register is set to “1”. As soon as the overtemperature condition is removed,

normal operation is automatically re-enable

d while the OTF bit is reset to “0” after a register

reading operation.
