APPLICATIONS
FUNCTIONAL PIN DESCRIPTION
APPLICATIONS
TYPICAL APPLICATION
Figure 7 shows a typical application for the 17529. When
applying the gate voltage to the CRES pin from an external
source, be sure to connect it via a resistor equal to, or greater
than, R G = V CRES / 0.02 Ω .
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.

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 pin (VM) (see Figure 8 ).
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
distances.
