)Requires a 150
resistor in GND connection. 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 10).
15)
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
I
IS
is zero and the diagnostic feedback potential
V
ST
is
High. See figure 2c, page 13.
