Fault conditions are considered as "outside" normal operating range. Protection functions are not designed for continuous repetitive operation. Short circuit current limit for max. duration of td(SC) max=400 µs, prior to shutdown 10) While demagnetizing load inductance, dissipated energy in PROFET is EAS= VON(CL) * iL(t) dt, approx. VON(CL) 2 ), see diagram page 8 EAS= 1/2 * L * IL * ( VON(CL) - Vbb 11) Reverse load current (through intrinsic drain-source diode) is normally limited by the connected load. Reverse current IGND of ≈ 0.3 A at Vbb= -32 V through the logic heats up the device. Time allowed under these condition is dependent on the size of the heatsink. Reverse IGND can be reduced by an additional external GND-resistor (150 Ω). Input and Status currents have to be limited (see max. ratings page 2 and circuit page 7).
