Pin
Name
Description
1
PWM
PWM input.
2
NC
No connection.
3
VDDI
Input-side power supply terminal; connect to a source of 4.5 to 5.5 V.
4
GNDI
Input-side ground terminal.
5
DISABLE Device Disable. When high, this input unconditionally drives outputs VOA, VOB LOW. It is
strongly recommended that this input be connected to external logic level to avoid erroneous
operation due to capacitive noise coupling.
6
DT
Dead time programming input. The value of the resistor connected from DT to ground sets the
dead time between output transitions of VOA and VOB. Defaults to 1 ns dead time when con-
7
NC
No connection.
8
VDDI
Input-side power supply terminal; connect to a source of 4.5 to 5.5 V.
9
GNDB
Ground terminal for Driver B.
10
VOB
Driver B output (low-side driver).
11
VDDB
Driver B power supply voltage terminal; connect to a source of 6.5 to 24 V.
12
NC
No connection.
13
NC
No connection.
14
GNDA
Ground terminal for Driver A.
15
VOA
Driver A output (high-side driver).
16
