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 4 and circuit page 9). 17) If ground resistors R GND are used, add the voltage drop across these resistors. 18) not subject to protection test, specified by design Data Sheet 7 V1.1, 2007-05-29 16) Smart High-Side Power Switch BTS5210L Truth Table ( each channel ) IN Normal operation Open load Overtemperature L H L H L H OUT L H Z H L L ST H H L19) H H L L = "Low" Level H = "High" Level X = don't care Z = high impedance, potential depends on external circuit Status signal valid after the time delay shown in the timing diagrams Parallel switching of channel 1 and 2 is easily possible by connecting the inputs and outputs in parallel (see truth table).
