MCP14700
Dual Input Synchronous MOSFET Driver
Features:
General Description:
• Ideally suited to drive low Figure-of-Merit (FOM)
MOSFETs such as Microchip’s MCP87000
MOSFET family
• Independent PWM Input Control for High-Side
and Low-Side Gate Drive
• Input Logic Level Threshold 3.0V TTL Compatible
• Dual Output MOSFET Drive for Synchronous
Applications
• High Peak Output Current: 2A (typical)
• Internal Bootstrap Blocking Device
• +36V BOOT Pin Maximum Rating
• Low Supply Current: 45 µA (typical)
• High Capacitive Load Drive Capability:
- 3300 pF in 10.0 ns (typical)
• Input Voltage Undervoltage Lockout Protection
• Overtemperature Protection
• Space Saving Packages:
- 8-Lead SOIC

The MCP14700 is a high-speed synchronous
MOSFET driver designed to optimally drive a high-side
and low-side N-Channel MOSFET. It is particularly well
suited for driving low-FOM MOSFETs, including
Microchip’s MCP87000 family of high-speed
MOSFETs. The MCP14700 has two PWM inputs to
allow independent control of the external N-Channel
MOSFETs. Since there is no internal cross conduction
protection circuitry the external MOSFET dead time
can be tightly controlled allowing for more efficient
systems or unique motor control algorithms.
The transition thresholds for the PWM inputs are
typically 1.6V on a rising PWM input signal and typically
1.2V on a falling PWM input signal. This makes the
MCP14700 ideally suited for controllers that utilize 3.0V
TTL/CMOS logic. The PWM inputs are internally pulled
low ensuring the output drive signals are low if the
inputs are floating.
The HIGHDR and LOWDR peak source current
capability of the MCP14700 device is typically 2A.
While the HIGHDR can sink 2A peak typically, the
LOWDR can sink 3.5A peak typically. The low
resistance pull-up and pull-down drive allow the
MCP14700 to quickly transition a 3300 pF load in
typically 10 ns. Bootstrapping for the high-side drive is
internally implemented which allows for a reduced
system cost and design complexity.
Applications:
• 3-Phase BLDC Motor Control
• High Efficient Synchronous DC/DC Buck
Converters
• High-Current Low Output Voltage Synchronous
DC/DC Buck Converters
• High Input Voltage Synchronous DC/DC Buck
Converters
• Core Voltage Supplies for Microprocessors
The MCP14700 features undervoltage lockout (UVLO)
with a typical hysteresis of 500 mV. Overtemperature
protection with hysteresis is also featured on the
device.

Supply Input Voltage (VCC)
The PHASE pin provides a return path for the high-side
gate driver. The source of the high-side and the drain of
the low-side power MOSFETs are connected to this
pin.
The VCC pin provides bias to the MCP14700 device. A
bypass capacitor is to be placed between this pin and
the GND pin. This capacitor should be placed as close
to the MCP14700 as possible.

High-Side PWM Control Input
Signal (PWMHI)
Floating Bootstrap Supply (BOOT)
The PWM input signal to control the high-side power
MOSFET is applied to the PWMHI pin. A logic high on
the PWMHI pin causes the HIGHDR pin to also
transition high.
The BOOT pin is the floating bootstrap supply pin for
the high-side gate drive. A capacitor is connected
between this pin and the PHASE pin to provide the
necessary charge to turn on the high-side power
MOSFET.
3.3
3.8
Low-Side PWM Control Input
Signal (PWMLO)
The PWM input signal to control the low-side power
MOSFET is applied to the PWMLO pin. A logic high on
the PWMLO pin causes the LOWDR pin to also
transition high.
3.4
Ground (GND)
The GND pin provides ground for the MCP14700
circuitry. It should have a low-impedance connection to
the bias supply source return. High peak currents will
flow out the GND pin when the low-side power
MOSFET is being turned off.
3.5
High-Side Gate Drive (HIGHDR)
The HIGHDR pin provides the gate drive signal to
control the high-side power MOSFET. The gate of the
high-side power MOSFET is connected to this pin.
3.9
Exposed Metal Pad (EP)
The exposed metal pad of the DFN package is not
internally connected to any potential. Therefore, this
pad can be connected to a ground plane or other
copper plane on a printed circuit board to aid in heat
removal from the package.
Low-side Gate Drive (LOWDR)
The LOWDR pin provides the gate drive signal to
control the low-side power MOSFET. The gate of the
low-side power MOSFET is connected to this pin.

DETAILED DESCRIPTION
4.1
Device Overview
When designing with the MCP14700 in applications
where cross conduction of the external MOSFETs is
not desired, care must be taken to ensure the PWM
inputs have the proper timing. There is no internal
cross conduction protection in the MCP14700.
The MCP14700 is a synchronous MOSFET driver with
dual independent PWM inputs capable of controlling
both a ground referenced and floating N-Channel
MOSFET. The PWM input threshold levels are truly
3.0V logic tolerant and have 400 mV of typical
hystereses making the MCP14700 ideal for use with
low-voltage controllers.
4.3
The UVLO feature of the MCP14700 does not allow the
HIGHDR or LOWDR output to function when the input
voltage, VCC, is below the UVLO threshold regardless
of the state of the PWMHI and PWMLO pins.
The MCP14700 is capable of suppling 2A (typical)
peak current to the floating high-side MOSFET that is
connected to the HIGHDR. With the exception of a
capacitor, all of the circuitry needed to drive this
high-side N-channel MOSFET is internal to the
MCP14700. A blocking device is placed between the
VCC and BOOT pins that allows the bootstrap capacitor
to be charged to VCC when the low-side power
MOSFET is conducting. Refer to the application
section, Section 5.1 “Bootstrap Capacitor Select”,
for information on determining the proper size of the
bootstrap capacitor. The HIGHDR is also capable of
sinking 2A (typical) peak current.
Once VCC reaches the UVLO threshold, the HIGHDR
and LOWDR outputs will respond to the state of the
PWMHI or PWMLO pins. There is a 500 mV hystereses
on the UVLO threshold.
4.4
Overtemperature Protection
The MCP14700 is protected from an overtemperature
condition by an internal thermal shutdown feature.
When the internal temperature of the MCP14700
reaches 147°C typically, the HIGHDR and LOWDR
outputs will transition to a low state regardless of the
state of the PWMHI or PWMLO pins. Once the internal
temperature is reduced by 20°C typically, the
MCP14700 will automatically respond to the states of
the PWMHI and PWMLO pins.
The LOWDR is capable of sourcing 2A (typical) peak
current and sinking 3.5A (typical) peak current. This
helps ensure that the low-side MOSFET stays turned
off during the high dv/dt of the PHASE node.
4.2

PWM Inputs
Timing Diagram
The PWM signal applied to the MCP14700 is supplied
by a controller IC. The timing diagram in Figure 4-1
graphically depicts the PWM signal and the output
signals of the MCP14700.
A logic high on either PWM pin causes the
corresponding output drive signal to be high. See
Figure 4-1 and Figure 4-2 for a graphical
representation of the MCP14700 operation. Internally
the PWM pins are pulled to ground to ensure there is
no drive signal to the external MOSFETs if the pins are
left floating. For reliable operation, it is recommended
that the rising and falling slew rate of the PWM signal
be faster than 1V/50 ns.

APPLICATION INFORMATION
5.3
5.1
Bootstrap Capacitor Select
The power dissipated in the MCP14700 consists of the
power loss associated with the quiescent power and
the gate charge power.
The selection of the bootstrap capacitor is based upon
the total gate charge of the high-side power MOSFET
and the allowable droop in gate drive voltage while the
high-side power MOSFET is conducting.
EQUATION 5-1:

The quiescent power loss can be calculated by the
following equation and is typically negligible compared
to the gate drive power loss.

For example:

CBOOT 0.15 uF
A low ESR ceramic capacitor is recommend with a
maximum voltage rating that exceeds the maximum
input voltage, VCC, plus the maximum supply voltage,
VSUPPLY. It is also recommended that the capacitance
of CBOOT does not exceed 1.2 uF.
5.2
Decoupling Capacitor
Proper decoupling of the MCP14700 is highly
recommended to help ensure reliable operation. This
decoupling capacitor should be placed as close to the
MCP14700 as possible. The large currents required to
quickly charge the capacitive loads are provided by this
capacitor. A low ESR ceramic capacitor is
recommended.
 2009-2013 Microchip Technology Inc.
The main power loss occurs from the gate charge
power loss. This power loss can be defined in terms of

PCB Layout
Proper PCB layout is important in a high current, fast
switching circuit to provide proper device operation.
Improper component placement may cause errant
switching, excessive voltage ringing, or circuit latch-up.
There are two important states of the MCP14700
outputs, high and low. Figure 5-1 depicts the current
flow paths when the outputs of the MCP14700 are high
and the power MOSFETs are turned on. The charge
needed to turn on the low-side power MOSFET comes
from the decoupling capacitor CVCC. The current flows
from this capacitor through the internal LOWDR
circuitry, into the gate of the low-side power MOSFET,
out the source, into the ground plane, and back to
CVCC. To reduce any excess voltage ringing or spiking,
the inductance and area of this current loop must be
minimized.
Figure 5-2 depicts the current flow paths when the
outputs of the MCP14700 are low and the power
MOSFETs are turned off. These current paths should
also have low inductance and a small loop area to
minimize the voltage ringing and spiking.

Turn On Current Paths.
The charge needed to turn on the high-side power
MOSFET comes from the bootstrap capacitor CBOOT.
Current flows from CBOOT through the internal
HIGHDR circuitry, into the gate of the high-side power
MOSFET, out the source and back to CBOOT. The
printed circuit board traces that construct this current
loop need to have a small area and low inductance. To
control the inductance, short and wide traces must be
used.
DS22201B-page 14
Turn Off Current Paths.
- The components that construct the high
current paths previously mentioned should be
placed close the MCP14700 device. The
traces used to construct these current loops
should be wide and short to keep the
inductance and impedance low.
- A ground plane should be used to keep both
the parasitic inductance and impedance
minimized. The MCP14700 device is capable
of sourcing and sinking high peaks current
and any extra parasitic inductance or
impedance will result in non-optimal
performance.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
