Description
Input-side ground terminal.
Non-inverting logic input terminal for Driver A.
Non-inverting logic input terminal for Driver B.
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.
No connection.
Input-side power supply terminal; connect to a source of 4.5 to 5.5 V.
Ground terminal for Driver B. GNDA and GNDB pins for the Si8236 are connected together
through the thermal pad.
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.GNDA and GNDB pins for the Si8236 are connected together
through the thermal pad.
Driver A output (high-side driver).
Driver A power supply voltage terminal; connect to a source of 6.5 to 24 V.
