Name
Description
SO
VFQFPN
1
33
LGATE1
Channel 1 LS driver output.
A little series resistor helps in reducing device-dissipated power.
2
34
VCCDR
LS drivers supply: it can be varied from 5V to 12V buses.
Filter locally with at least 1
F ceramic cap vs. PGND.
3
35
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.
4
36
UGATE1
Channel 1 HS driver output.
A little series resistor helps in reducing device-dissipated power.
5
2
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).
6
4
VCC
Device supply voltage. The operative supply voltage is 12V ±10%.
Filter with 1
F (Typ.) capacitor vs. GND.
7
5,6
SGND
All the internal references are referred to this pin. Connect it to the PCB signal
ground.
8
7
COMP
This pin is connected to the error amplifier output and is used to compensate the
control feedback loop.
9
8
FB
This pin is connected to the error amplifier inverting input and is used to
compensate the control feedback loop.
