Function
Channel 1 HS driver output.
A small series resistors 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 resistor in series to the boot diode helps in reducing
Boot capacitor overcharge.
Not internally connected.
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.
Channel 3 HS driver output.
A small series resistors helps in reducing device-dissipated power.
Channel 3 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE3 and provide necessary
Bootstrap diode.A small resistor in series to the boot diode helps in reducing
Boot capacitor overcharge.
Not internally connected.
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.Leave floating when using 2 Phase operation.
Channel 2 HS driver output.
A small series resistors helps in reducing device-dissipated power.
Leave floating when using 2 Phase operation.
Channel 2 HS driver supply.
Connect through a capacitor (100nF typ.) to PHASE2 and provide necessary
Bootstrap diode.A small resistor in series to the boot diode helps in reducing
Boot capacitor overcharge.Leave floating when using 2 Phase operation.
Not internally connected.
Not internally connected.
Not internally connected.
Not internally connected.
Device Supply Voltage. The operative voltage is 12V ±15%. Filter with 1µF (typ)
MLCC vs. SGND.
PHASE SELection Pin.Internally pulled up by 12.5µA(typ) to 5V.
It allows selecting between 2 Phase and 3 Phase operation.See
for
details.
OUTput ENable Pin.Internally pulled up by 12.5µA(typ) to 5V.
Forced low, the device stops operations with all MOSFETs OFF: all the
protections are disabled except for
Leave floating, the device starts-up implementing soft-start up to the selected
VID code.
Cycle this pin to recover latch from protections; filter with 1nF (typ) vs. SGND.
