PROTECTIONS (see note 1)

Note 1: To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals must be used

together with a proper software strategy. If the device is subjected to abnormal conditions, this software must limit the duration and number

of activation cycles
