CEMF SNUBBING TECHNIQUES
Care must be taken to protect the IC from potentially
damaging CEMF spikes induced when commutating currents
in inductive loads. Typical practice is to provide snubbing of
voltage transients by placing a zener or capacitor at the
supply pin (VM) (see Figure 7 ).
PCB LAYOUT
When designing the printed circuit board (PCB), connect
sufficient capacitance between power supply and ground
pins to ensure proper filtering from transients. For all high-
current paths, use wide copper traces and shortest possible
distance.

Although VM1 and VM2 are connected internally, they
must be connected externally to attain sufficient power
distribution.
Take precautions to guard against electrostatic discharge
when handling the device, especially when mounting and
demounting the device to a PCB.
