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 at-
tempting 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 8 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.
Although the LM9061 will drive MOSFETs from any manu-
facturer, National Semiconductor offers a wide range of
power MOSFETs. Figure 9 shows a small sample of the
devices available.
