Additional output resistance is added with SMD resistors. A diode is provided to allow control of turn-off separately. The diode makes the effective

turn-off resistance be the parallel combination of the R

GEXT-ON

and R

GEXT-OFF

while the turn-on effective resistance is R

GEXT-ON

. Standard value is 4.99 Ω for

both turn-on and turn-off. See Figure 1 for configuration.

Soft-Shutdown Resistor will safely turn off the Gate in the event an over-current is detected by the Desaturation Protection circuit.
