9A Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS Process

Master Instrument Corporation 

Micrel, Inc.

PT = Power dissipated in a driver when the output

changes states (“shoot-through current”) in

Watts. NOTE: The “shoot-through” current

from a dual transition (once up, once down)

for both drivers is stated in Figure 7 in

ampere-nanoseconds. This figure must be

multiplied by the number of repetitions per

second (frequency) to find Watts.

RO = Output resistance of a driver in Ohms.

VS = Power supply voltage to the IC in Volts.
