INCREASING MOSFET TURN ON TIME
The ability of the LM9061 to quickly turn on the MOSFET is an important factor in the management of the
MOSFET power dissipation. Caution should be exercised when attempting to increase the MOSFET Turn On
time by limiting the Gate drive current. The MOSFET average dissipation, and the LM9061 Delay time, must be
recalculated with the extended switching transition time.
Figure 22 shows a method of increasing the MOSFET Turn On time, without affecting the Turn Off time. In this
method the Gate is charged at an exponential rate set by the added external Gate resistor and the MOSFET
Gate capacitances.
