VCCDR3
Channel 3 LS driver supply: it can be varied from 5V to 12V buses.
It must be connected together with other VCCDRx pins.
Filter locally with at least 1
μ
F ceramic cap vs. PGND3.
Channel 2 LS driver return path.
Connect to Power Ground Plane.
Channel 2 LS driver output.
A little series resistor helps in reducing device-dissipated power.

F ceramic cap vs. PGND2.
Channel 2 HS driver return path. It must be connected to the HS2 mosfet source and provides
the return path for the HS driver of channel 2.
Channel 2 HS driver output.
A little series resistor helps in reducing device-dissipated power.
Channel 2 HS driver supply. This pin supplies the relative high side driver.
Connect through a capacitor (100nF Typ.) to the PHASE2 pin and through a diode to VCC (cath-
ode vs. boot).
Channel 1 HS driver supply. This pin supplies the relative high side driver.
Connect through a capacitor (100nF Typ.) to the PHASE1 pin and through a diode to VCC (cath-
ode vs. boot).
Channel 1 HS driver output.
A little series resistor helps in reducing device-dissipated power.
Channel 1 HS driver return path. It must be connected to the HS1 mosfet source and provides
the return path for the HS driver of channel 1.
Not internally connected.
Thermal pad connects the silicon substrate and makes a good thermal contact with the PCB to
dissipate the power necessary to drive the external mosfets. Connect to the GND plane with sev-
eral vias to improve thermal conductivity.
