PIN DESCRIPTIONS
Pin
Name Description Application Information
SOIC WSON
Locally decouple to V
SS
using ESR/ESL capacitor, located
1 1 V
DD
Positive gate drive supply
as close to IC as possible.
Connect the positive terminal to bootstrap capacitor to the
HB pin and connect negative terminal to HS. The
2 2 HB High side gate driver bootstrap rail
Bootstrap capacitor should be placed as close to IC as
possible
Connect to gate of high side MOSFET with short low
3 3 HO High side gate driver output
inductance path.
Connect to bootstrap capacitor negative terminal and
4 4 HS Highside MOSFET source connection
source of high side MOSFET.
Resistor from RT to ground programs the deadtime
between high and low side transitions. The resistor should
5 7 RT Deadtime programming pin
be located close to the IC to minimize noise coupling from
adjacent traces.
Logic 1 equals High Side ON and Low Side OFF. Logic 0
6 8 IN Control input
equals High Side OFF and Low Side ON.
7 9 V
SS
Ground return All signals are referenced to this ground.
Connect to the gate of the low side MOSFET with a short
8 10 LO Low side gate driver output
low inductance path.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under
which operation of the device is specified. Operating Ratings do not imply performance limits. For performance limits and associated test
conditions, see Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The human body model is a 100 pF capacitor discharged through a 1.5kΩ resistor into each pin. 2 kV for all pins except Pin 2, Pin 3 and
Pin 4 which are rated at 500V.
