9LGATE2
Channel 2 LS Driver Output.
A small series resistor helps in reducing device-dissipated power.
10
LGATE3
Channel 3 LS Driver Output.
A small series resistor helps in reducing device-dissipated power.
11
BOOT1
Channel 1 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE1 and provide
necessary Bootstrap diode.
A small series resistor before the boot diode helps in reducing Boot
capacitor overcharge.
12
UGATE1
Channel 1 HS driver output.
A small series resistors helps in reducing device-dissipated power.
13
PHASE1
Channel 1 HS driver return path.
It must be connected to the HS1 mosfet source and provides return path
for the HS driver of channel 1.
14
BOOT2
Channel 2 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE2 and provide
necessary Bootstrap diode.
A small series resistor before the boot diode helps in reducing Boot
capacitor overcharge.
15
UGATE2
Channel 2 HS driver output.
A small series resistors helps in reducing device-dissipated power.
16
PHASE2
Channel 2 HS driver return path.
It must be connected to the HS2 mosfet source and provides return path
for the HS driver of channel 2.
17
BOOT3
Channel 3 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE3 and provide
necessary Bootstrap diode.
A small series resistor before the boot diode helps in reducing Boot
capacitor overcharge.
18
UGATE3
Channel 3 HS driver output.
A small series resistors helps in reducing device-dissipated power.
19
PHASE3
Channel 3 HS driver return path.
It must be connected to the HS3 mosfet source and provides return path
for the HS driver of channel 3.
20
N.C.
Not Internally Bonded.
21
PGOOD
Open Drain Output set free after SS has finished and pulled low when
VSEN is lower than the relative threshold. Pull up to a voltage lower than
5V (typ), if not used it can be left floating.
22
N.C.
Not Internally Bonded.
