Input-side ground terminal.
PWM input.
No connection.
Input-side power supply terminal; connect to a source of 4.5 to 5.5 V.
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.
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 connected to VDDI or left open (see "3.8.Programmable Dead Time and
Overlap Protection" on page 26).
Input-side power supply terminal; connect to a source of 4.5 to 5.5 V.
Ground terminal for Driver B.
Driver B output (low-side driver).
Driver B power supply voltage terminal; connect to a source of 6.5 to 24 V.
No connection.
Ground terminal for Driver A.
Driver A output (high-side driver).
Driver A power supply voltage terminal; connect to a source of 6.5 to 24 V.
