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

undervoltage threshold. If the supply voltage drops below the
undervoltage threshold, the output power stage switches to a
tri-state condition. When the supply voltage returns to a level
that is above the threshold, the power stage automatically
resumes normal operation according to the established
condition of the input terminals.
