HS driver output.
It must be connected to the HS MOSFET gate. A small series resistors helps in
reducing device-dissipated power.
HS driver supply.
Connect through a capacitor (100 nF typ.) to PHASE and provide necessary
Bootstrap diode. A small resistor in series to the boot diode helps in reducing
Boot capacitor overcharge.
Exposed pad connects the silicon substrate. As a consequence it makes a
good thermal contact with the PCB to dissipate the power necessary to drive
the external MOSFETs.
Connect it to the power ground plane using 4.3 x 4.3 mm square area on the
PCB and with nine vias, to improve thermal conductivity.
