BOOT1 and BOOT2
These pins provide bias voltage to the upper MOSFET
drivers. A single capacitor bootstrap circuit may be used to
create a BOOT voltage suitable to drive a standard N-
Channel MOSFET.
UGATE1 and UGATE2
Connect UGATE1 and UGATE2 to the corresponding upper
MOSFET gate. These pins provide the gate drive for the
upper MOSFETs. UGATE2 is also monitored by the adaptive
shoot through protection to determine when the upper FET
of the V
TT
regulator has turned off.
LGATE1 and LGATE2
Connect LGATE1 and LGATE2 to the corresponding lower
MOSFET gate. These pins provide the gate drive for the
lower MOSFETs. These pins are monitored by the adaptive
shoot through protection to determine when the lower FET
has turned off.
PGND1 and PGND2
These are the power ground connections for the gate drivers
of the PWM controllers. Tie these pins to the ground plane
through the lowest impedence connection available.
OCSET/SD
A resistor (R
OCSET
) connected from this pin to the drain of
the upper MOSFET of the V
DDQ
regulator sets the
overcurrent trip point. R
OCSET
, an internal 40
μ
A current
source (I
OCS
), and the upper MOSFET on-resistance
(r
DS(ON)
) set the V
DDQ
converter over-current (OC) trip
point according to the following equation:
I
DS ON
)
An overcurrent trip cycles the soft-start function.
Pulling the OCSET/SD pin to ground resets the ISL6530 and
all external MOSFETS are turned off allowing the two output
voltage power rails to float.
PGOOD
A high level on this open-drain output indicates that both the
V
DDQ
and V
TT
regulators are within normal operating
voltage ranges.
GNDA
Signal ground for the IC. Tie this pin to the ground plane
through the lowest impedence connection available.
VCC
The 5V bias supply for the chip is connected to this pin. This
pin is also the positive supply for the lower gate driver,
LGATE2. Connect a well decoupled 5V supply to this pin.
V2_SD
A high level on the V2_SD input places the V2 controller into
“sleep” mode. In sleep mode, both UGATE2 and LGATE2
are driven low, effectively floating the V
TT
supply.
