C1L and C1H, C2L and C2H
These two pairs of terminals, the C1L and C1H and the C2L
and C2H, connect to the external bucket capacitors required by
the internal charge pump. The typical value for the bucket
capacitors is 0.1
μ
F.
GOUT
The GOUT output terminal provides a level-shifted, high-side
gate drive signal to an external MOSFET with C
iss
up to 500 pF.
V
DD
The V
DD
terminal carries the 5.0 V supply voltage and
current into the logic sections of the IC. V
DD
has an
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.
APPLICATIONS
Figure 4
shows a typical application for the 17511A. 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
=

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 via placing a capacitor or zener at the supply
terminal (VM) (see
Figure 5
).
