Application Information
Power Supplies and Bypassing
The recommended supply connections are shown in
Figure 16. A floating power supply (which in many ap-
plications could be the same supply that is used to drive
the high-side power transistor) is regulated to 5 V using
a simple zener diode (D1); the value of resistor R4 should
be chosen to supply sufficient current from the existing
floating supply. The voltage from the current sensing
resistor (Rsense) is applied to the input of the HCPL-7510
through an RC anti-aliasing filter (R2 and C2). Although
the application circuit is relatively simple, a few recom-
mendations should be followed to ensure optimal per-
formance.

The power supply for the HCPL-7510 is most often
obtained from the same supply used to power the
power transistor gate drive circuit. If a dedicated supply
is required, in many cases it is possible to add an ad-
ditional winding on an existing transformer. Otherwise,
some sort of simple isolated supply can be used, such as
a line powered transformer or a high-frequency DC-DC
converter.
An inexpensive 78L05 three-terminal regulator can also
be used to reduce the floating supply voltage to 5 V. To
help attenuate high- frequency power supply noise or
ripple, a resistor or inductor can be used in series with the
input of the regulator to form a low-pass filter with the
regulator’s input bypass capacitor.
