APPLICATIONS
FUNCTIONAL TERMINAL DESCRIPTION
APPLICATIONS
TYPICAL APPLICATION
Figure 7
shows a typical application for the 17529. When
applying the gate voltage to the C
RES
terminal from an
external source, be sure to connect it via a resistor equal to,
or greater than, R
G
=
V
CRES
/ 0.02
.
The internal charge pump of this device is generated from
the VDD supply; therefore, care must be taken to provide
sufficient gate-source voltage for the high-side MOSFETs
when V
M
>> V
DD
(e.g., V
M
= 5.0 V, V
DD
= 3.0 V), in order to
ensure full enhancement of the high-side MOSFET channels.

CONDUCTED ELECTROMOTIVE FORCE (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 capacitor or zener at the
supply terminal (VM) (see
Figure 8
).
Figure 8. CEMF Snubbing Techniques
PCB LAYOUT
When designing the printed circuit board (PCB), connect
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.
