It is designed for all kind of resistive and inductive loads (relays, solenoid) in automotive and industrial applications. Protection Functions • Over voltage protection: An internal clamp limits the output voltage at VDS(AZ) (min. 60V) when inductive loads are switched off. • Current limitation: By means of an internal current measurement the drain current is limited at ID(lim) (1.4 - 1.5 A typ.). If the current limitation is active the device operates in the linear region, so power dissipation may exceed the capability of the heatsink. This operation leads to an increasing junction temperature until the over temperature threshold is reached. • Over temperature and short circuit protection: This protection is based on sensing the chip temperature. The location of the sensor ensures a fast and accurate junction temperature detection. Over temperature shutdown occurs at minimum 150 °C. A hysteresis of typ. 10 K enables an automatic restart by cooling. The device is ESD protected according Human Body Model (4 kV) and load dump protected (see Maximum Ratings).
