Functional Pin Description
UGATE (Pin 1), (Pin 16 QFN)
Upper gate drive output. Connect to gate of high-side power N-
Channel MOSFET.
BOOT (Pin 2), (Pin 2 QFN)
Floating bootstrap supply pin for the upper gate drive. Connect a
bootstrap capacitor between this pin and the PHASE pin. The
bootstrap capacitor provides the charge to turn on the upper
MOSFET. A resistor in series with boot capacitor is required in
certain applications to reduce ringing on the BOOT pin. See
“Internal Bootstrap Device” on page 7 for guidance in choosing
the appropriate capacitor and resistor values.
PWM (Pin 3), (Pin 3 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” on page 7 for further details. Connect this pin to the
PWM output of the controller.
GND (Pin 4), (Pin 4 QFN)
Bias and reference ground. All signals are referenced to this
node.
PGND (Pin 5 QFN Package Only)
This pin is the power ground return for the lower gate driver.
LGATE (Pin 5), (Pin 7 QFN)
Lower gate drive output. Connect to gate of the low-side power N-
Channel MOSFET.
VCC (Pin 6), (Pin 9 QFN)
Connect this pin to a +12V bias supply. Place a high quality bypass
capacitor from this pin to GND.
LVCC (Pin 10 QFN Package Only)
Timing Diagram
Lower gate driver supply voltage.
PVCC (Pin 7), (Pin 11 QFN)
For the HIP6601B and the HIP6604B, this pin supplies the upper gate
drive bias. Connect this pin from +12V down to +5V.
For the HIP6603B, this pin supplies both the upper and lower gate
drive bias. Connect this pin to either +12V or +5V.
PHASE (Pin 8), (Pin 14 QFN)
Connect this pin to the source of the upper MOSFET and the drain
of the lower MOSFET. The PHASE voltage is monitored for
adaptive shoot-through protection. This pin also provides a return
path for the upper gate drive.
Description
Operation
Designed for versatility and speed, the HIP6601B, HIP6603B and
HIP6604B dual MOSFET drivers control both high-side and low-
side N-Channel FETs from one externally provided PWM signal.
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” on page 4), the PWM
signal takes control of gate transitions. A rising edge on PWM
initiates the turn-off of the lower MOSFET (see “Timing Diagram”
on page 6). After a short propagation delay [t PDLLGATE ], the
lower gate begins to fall. Typical fall times [t FLGATE ] are
provided in the “Electrical Specifications” on page 4. Adaptive
shoot-through circuitry monitors the LGATE voltage and
determines the upper gate delay time [t PDHUGATE ] 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 [t RUGATE ] and the upper MOSFET turns on.
