docid022375 rev 9 29/48 vnd7140aj-e protections 47 3 protections 3.1 power limitation the basic working principle of this protection consists of an indirect measurement of the junction temperature swing t j through the direct measurement of the spatial temperature gradient on the device surface in order to automatically shut off the output mosfet as soon as t j exceeds the safety level of t j_sd . according to the voltage level on the faultrst pin, the output mosfet switches on and cycles with a thermal hysteresis according to the maximum instantaneous power which can be handled (faultrst = low) or remains off (faultrst = high). the protection prevents fast thermal transient effects and, consequently, reduces thermo-mechanical fatigue. 3.2 thermal shutdown in case the junction temperature of the device exceeds the maximum allowed threshold (typically 175c), it automatically switches off and the diagnostic indication is triggered. according to the voltage level on the faultrst pin, the device switches on again as soon as its junction temperature drops to t r (see ta ble 8 , faultrst = low) or remains off (faultrst = high). 3.3 current limitation the device is equipped with an output current limiter in order to protect the silicon as well as the other components of the system (e.g. bonding wires, wiring harness, connectors, loads, etc.) from excessive current flow. consequently, in case of short circuit, overload or during load power-up, the output current is clamped to a safety level, i limh , by operating the output power mosfet in the active region. 3.4 negative voltage clamp in case the device drives inductive load, the output voltage reaches negative value during turn off. a negative voltage clamp structure limits the maximum negative voltage to a certain value, v demag (see tab le 8 ), allowing the inductor energy to be dissipated without damaging the device.
