Dual Channel Synchronous Rectified
Buck MOSFET Driver
The HIP6602B is a high frequency, two power channel
MOSFET driver specifically designed to drive four power
N-Channel MOSFETs in a synchronous rectified buck
converter topology. This device is available in either a
14-lead SOIC or a 16-lead QFN package with a PAD to
thermally enhance the package. These drivers combined
with a HIP63xx or ISL65xx series of Multi-Phase Buck PWM
controllers and MOSFETs form a complete core voltage
regulator solution for advanced microprocessors.
The HIP6602B drives both upper and lower gates over a
range of 5V to 12V. This drive-voltage flexibility provides the
advantage of optimizing applications involving trade-offs
between switching losses and conduction losses.
The output drivers in the HIP6602B have the capacity to
efficiently switch power MOSFETs at high frequencies. Each
driver is capable of driving a 3000pF load with a 30ns
propagation delay and 50ns transition time. This device
implements bootstrapping on the upper gates with a single
external capacitor and resistor required for each power
channel. This reduces implementation complexity and allows
the use of higher performance, cost effective, N-Channel
MOSFETs. Adaptive shoot-through protection is integrated
to prevent both MOSFETs from conducting simultaneously.

material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations.
Intersil Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.

Functional Pin Descriptions
PWM1 (Pin 1) and PWM2 (Pin 2), (Pins 15 and 16
QFN)
The PWM signal is the control input for the driver. The PWM
signal can enter three distinct states during operation, see the
three-state PWM Input section under DESCRIPTION for further
details. Connect this pin to the PWM output of the controller.
GND (Pin 3), (Pin 1 QFN)
Bias and reference ground. All signals are referenced to
this node.
LGATE1 (Pin 4) and LGATE2 (Pin 7), (Pins 2 and
6 QFN)
Lower gate drive outputs. Connect to gates of the low-side
power N-Channel MOSFETs.
PVCC (Pin 5), (Pin 3 QFN)
This pin supplies the upper and lower gate drivers bias.
Connect this pin from +12V down to +5V.
PGND (Pin 6), (Pin 4 QFN)
This pin is the power ground return for the lower gate
drivers.
PHASE2 (Pin 8) and PHASE1 (Pin 13), (Pins 7 and
13 QFN)
Connect these pins to the source of the upper MOSFETs
and the drain of the lower MOSFETs. The PHASE voltage is
monitored for adaptive shoot-through protection. These pins
also provide a return path for the upper gate drive.
UGATE2 (Pin 9) and UGATE1 (Pin 12), (Pins 9 and
12 QFN)
Upper gate drive outputs. Connect to gate of high-side
power N-Channel MOSFETs.
Timing Diagram.
BOOT 2 (Pin 10) and BOOT 1 (Pin 11), (Pins 10 and
11 QFN)
Floating bootstrap supply pins for the upper gate drivers.
Connect a bootstrap capacitor between these pins and the
corresponding PHASE pin. The bootstrap capacitor provides
the charge to turn on the upper MOSFETs. A resistor in
series with boot capacitor is required in certain applications
to reduce ringing on the BOOT pin. See the Internal
Bootstrap Device section under DESCRIPTION for guidance
in choosing the appropriate resistor and capacitor value.
VCC (Pin 14), (Pin 14 QFN)
Connect this pin to a +12V bias supply. Place a high quality
bypass capacitor from this pin to GND. To prevent forward
biasing an internal diode, this pin should be more positive
then PVCC during converter start-up
Description
Operation
Designed for versatility and speed, the HIP6602B two channel,
dual MOSFET driver controls both high-side and low-side
N-Channel FETs from two externally provided PWM signals.
The upper and lower gates are held low until the driver is
initialized. Once the VCC voltage surpasses the VCC Rising
Threshold (See Electrical Specifications), the PWM signal
takes control of gate transitions. A rising edge on PWM
initiates the turn-off of the lower MOSFET (see Timing
Diagram). After a short propagation delay [TPDLLGATE], the
lower gate begins to fall. Typical fall times [TFLGATE] are
provided in the Electrical Specifications section. Adaptive
shoot-through circuitry monitors the LGATE voltage and
determines the upper gate delay time [TPDHUGATE] based
on how quickly the LGATE voltage drops below 2.2V. This
prevents both the lower and upper MOSFETs from
conducting simultaneously or shoot-through. Once this delay
period is complete the upper gate drive begins to rise
[TRUGATE] and the upper MOSFET turns on.
