Application note
TDE1897C, TDE1897R, TDE1898C and TDE1898R
in extreme overload conditions

Introduction
The purpose of this document is to provide the circuit designer with some insight into how
the TDE1897C, TDE1897R, TDE1898C and TDE1898R devices behave in extreme
overload conditions. Although the conditions may range outside the limits of the guaranteed
performances described in the device datasheet, erroneous connections during the
installation phase may occur and momentarily create such conditions. The pe
