Recommended Protection for
Output Transistors
During switching transitions, the
output transistors Q1 and Q2 of
the HCPL-3100/3101 can
conduct large amounts of
current. Figure 1 describes a
recommended circuit design
showing a current limiting
resistor R₂ which is necessary in
order to prevent damage to the
output transistors Q1 and Q2.
(See Note 7.) A bypass capacitor
C₁ is also recommended to
reduce power supply noise.
