TYPICAL APPLICATION
applying the gate voltage to the C
external source, be sure to connect it via a resistor equal to,
or greater than, R
CONDUCTED ELECTROMOTIVE FORCE (CEMF)
SNUBBING TECHNIQUES
damaging CEMF spikes induced when commutating currents
in inductive loads. Typical practice is to provide snubbing of
voltage transients by placing a capacitor or zener at the
supply terminal (VM) (see

sufficient capacitance between power supply and ground
terminals to ensure proper filtering from transients. For all
high-current paths, use wide copper traces and shortest
possible distances.
