Channel 2 LS Driver Output.
A small series resistor helps in reducing device-dissipated power.
Channel 3 LS Driver Output.
A small series resistor helps in reducing device-dissipated power.
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.
Channel 1 HS driver output.
A small series resistors helps in reducing device-dissipated power.
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.
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.
Channel 2 HS driver output.
A small series resistors helps in reducing device-dissipated power.
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.
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.
Channel 3 HS driver output.
A small series resistors helps in reducing device-dissipated power.
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.
Not Internally Bonded.
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.
Not Internally Bonded.
