Pins description and connection diagrams
11/50
45
BOOT1
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
(cathode vs. boot).
46
UGATE1
Channel 1 HS driver output.
A little series resistor helps in reducing device-dissipated power.
47
PHASE1
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.
48
N.C.
Not internally connected.
PAD
THERMAL
PAD
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
several vias to improve thermal conductivity.
