The reverse load current through the intrinsic drain-source diode has to be limited by the connected load. Power dissipation is higher compared to normal operating conditions due to the voltage drop across the drain-source diode. The temperature protection is not active during reverse current operation! Input and Status currents have to be limited (see max. ratings page 3 and circuit page 9). 16) This range for the current sense ratio refers to all devices. The accuracy of the k ILIS can be raised at least by a factor of two by matching the value of k ILIS for every single device. In the case of current limitation the sense current IIS is zero and the diagnostic feedback potential VST is High. See figure 2c, page 12. 17) Valid if Vbb(u rst) was exceeded before. 18) not subject to production test, specified by design 19) External pull up resistor required for open load detection in off state. |
