Thermal data

UGATE

HS driver output.

It must be connected to the HS MOSFET gate. A small series resistors helps in

reducing device-dissipated power.

BOOT

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.

PAD

Thermal

PAD

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.
