EAS= 1/2 * L * I L * ( ON(CL) V - V ), see diagram page 8ON(CL) bb 10) 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).
