1
The resistance of the internal transistor which discharges the power MOSFET gate capacitance when overload protection operates.
The external drive circuit should be such that the input voltage does not exceed V
IS(TO)
minimum when the overload protection has
operated. Refer also to figure for latched input characteristics.
2
Applications using a lower value for R
IS
would require external overvoltage protection.
3
For applications requiring a lower value for R
I
, an external overload protection strategy is possible using the flag pin to ‘tell’ the control circuit to
switch off the input.
