pin FuncTions
V
CC
(Pin 1): Chip Supply. This pin powers the internal low
side circuitry. A low ESR ceramic bypass capacitor should
be tied between this pin and the GND pin (Pin 2).
GND (Pin 2): Chip Ground.
INP (Pin 3): Input Signal. TTL/CMOS compatible input
referenced to GND (Pin 2).
TS (Pin 4): Top (High Side) source connection or GND if
used in ground referenced applications.
TG (Pin 5): High Current Gate Driver Output (Top Gate).
This pin swings between TS and BOOST.
BOOST (Pin 6): High Side Bootstrapped Supply. An ex
-
ternal capacitor should be tied between this pin and TS
(Pin4). Normally, a bootstrap diode is connected between
V
CC
(Pin1) and this pin. Voltage swing at this pin is from
V
CC
– V
D
to V
IN
+ V
CC
– V
D
, where V
D
is the forward volt-
age drop of the bootstrap diode.

(Pin 3): Chip Supply. This pin powers the internal low
side circuitry. A low ESR ceramic bypass capacitor should
be tied between this pin and the GND pin (Pin 2).
NC (Pin 5): No Connect. No connection required. For
convenience, this pin may be tied to Pin 6 (BOOST) on
the application board.
BOOST (Pin 6): High Side Bootstrapped Supply. An external
capacitor should be tied between this pin and TS (Pin8).
Normally, a bootstrap diode is connected between V
CC

TS (Pin 8): Top (High Side) source connection or GND if
used in ground referenced applications.
Exposed Pad (Pin 9): Ground. Must be electrically con
-
nected to Pins 2 and 4 and soldered to PCB ground for
optimum thermal performance.
