Be sure to make each terminal of Rch to an OPEN state or to connect to VSS in Monophonic mode. In addition, as

for a High-side terminal, be sure to make it to an OPEN state and to connect to VBS.

Low-Side Driver means the PowerMOSFET (Nch). High-Side Driver means the PowerMOSFET(Pch).

The through rate control of PowerMOSFET is performed by connecting a resistor between the pull-up side output

of a Low-Side driver and PowerMOSFET (Nch) and between the pull-down side of a High-Side driver and

PowerMOSFET (Pch).
