34
PSI
Power saving indicator pin.
Connect to the PSI pin of the CPU to manage low-power state.
When asserted (pulled low), the controller will act as programmed on the OCSET/PSI_A.
35
SSEND
Soft-start END signal.
Open drain output sets free after ss has finished and pulled low when triggering any
protection. Pull up to a voltage lower than 3.3 V, if not used it can be left floating.
36
BOOT3
Channel 3 HS driver supply.
Connect through a capacitor (100 nF typ.) to PHASE3 and provide necessary bootstrap
diode.A small resistor in series to the boot diode helps in reducing boot capacitor overcharge.
37
UGATE3
Channel 3HS driver output.
It must be connected to the HS3 MOSFET gate. A small series resistors helps in reducing
device-dissipated power.
38
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.
39
BOOT2
Channel 2 HS driver supply.
Connect through a capacitor (100 nF 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.
40
UGATE2
Channel 2HS driver output.
It must be connected to the HS2 MOSFET gate. A small series resistors helps in reducing
device-dissipated power. Leave floating when using 2-Phase operation.
41
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. Leave floating when using 2-phase operation.
42
VCCDR
LS Driver Supply. VCDDR pin voltage has to be the same of VCC pin.
Filter with 2 x 1 F MLCC capacitor vs. PGND.
43
LGATE3
Channel 3LS driver output.
A small series resistor helps in reducing device-dissipated power.
44
LGATE2
Channel 2LS driver output.
A small series resistor helps in reducing device-dissipated power.
Leave floating when using 2-phase operation.
45
LGATE1
Channel 1LS driver output.
A small series resistor helps in reducing device-dissipated power.
46
N.C.
Not internally connected.
47
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.
