Add RIN for reverse battery protection in applications with Vbb above 16V; recommended value: V ZL 0.08 A 1 1 + = RIN RIS | Vbb | -12V To minimise power dissipation at reverse battery operation, the overall current into the IN and IS pin should be about 80mA. The current can be provided by using a small signal diode D in parallel to the input switch, by using a MOSFET input switch or by proper adjusting the current through RIS. Since the current via Rbb generates additional heat in the device, this has to be taken into account in the overall thermal consideration. Inverse load current operation Vbb V bb - IL IN + PROFET V OUT + IS - OUT IIS V IN V IS R IS - The device can be operated in inverse load current mode (VOUT > Vbb > 0V). The current sense feature is not available during this kind of operation (IIS = 0). In case of inverse operation the intrinsic drain source diode is eventually conducting resulting in considerably increased power dissipation. The transition from inverse to forward mode can result in a delayed switch on. Note: Temperature protection during inverse load current operation is not possible!
