The MCP14E6/7/8 devices are high-speed MOSFET
drivers, capable of providing 2.0A of peak current. The
dual inverting, dual non-inverting and complementary
outputs are directly controlled from either TTL or
CMOS (3V to 18V). These devices also feature low
shoot-through current, fast rise/fall times and
propagation delays, which make them ideal for high
switching frequency applications.

The MCP14E6/7/8 devices operate from a 4.5V to 18V
single power supply and can easily charge and
discharge 1000 pF of MOSFET gate capacitance. They
provide low enough impedances, in both the ON and
OFF states, to ensure the MOSFETs’ intended state
will not be affected, even by large transients.
The additional control of the MCP14E6/7/8 outputs is
allowed by the use of separate enable functions. The
ENB_A and ENB_B pins are active-high and are
internally pulled up to VDD. The pins may be left floating
for standard operation.
The MCP14E6/7/8 dual output, 2.0A driver family is
offered in both surface-mount and pin-through-hole
packages with a -40oC to +125oC temperature rating.
The low thermal resistance of the thermally enhanced
DFN package allows greater power dissipation
capability for driving heavier capacitive or resistive
loads.
These devices are highly latch-up resistant under any
conditions within their power and voltage ratings. They
are not subject to damage when up to 5V of noise
spiking (of either polarity) occurs on the ground pin.
The devices are fully latch-up protected when tested
according to JEDEC JESD78A. All terminals are fully
protected against Electrostatic Discharge (ESD), up to
4 kV (HBM) or 400V (MM).

Supply Input (VDD)
The ENB_A pin is the enable control for Output A. This
enable pin is internally pulled up to VDD for active-high
operation and can be left floating for standard operation. When the ENB_A pin is pulled below the enable
pin, Low Level Input Voltage (VEN_L), Output A will be
in the OFF state, regardless of the input pin state.
VDD is the bias supply input for the MOSFET driver and
has a voltage range of 4.5V to 18V. This input must be
decoupled to ground with a local ceramic capacitor.
This bypass capacitor provides a localized lowimpedance path for the peak currents that are provided
to the load.
3.2
3.6
Control Inputs A and B (IN A; IN B)
The MOSFET driver inputs are a high-impedance
TTL/CMOS compatible input. The inputs also have
hysteresis between the high and low input levels,
allowing them to be driven from slow rising and falling
signals, and to provide noise immunity.
3.3
Ground (GND)
Ground is the device return pin. The ground pin should
have a low-impedance connection to the bias supply
source return. High peak currents will flow out the
ground pin when the capacitive load is being
discharged.
3.4
Enable B (ENB_B)
The ENB_B pin is the enable control for Output B. This
enable pin is internally pulled up to VDD for active-high
operation, and can be left floating for standard operation. When the ENB_B pin is pulled below the enable
pin, Low-Level Input Voltage (VEN_L), Output B will be
in the OFF state, regardless of the input pin state.
3.7
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.
Outputs A and B (OUT A; OUT B)
Outputs, A and B, are CMOS push-pull outputs that are
capable of sourcing and sinking 2.0A of peak current
(VDD = 18V). The low output impedance ensures the
gate of the MOSFET will stay in the intended state,
even during large transients.

APPLICATION INFORMATION
4.1
General Information
VDD = 18V
1 µF
MOSFET drivers are high-speed, high-current devices
which are intended to source/sink high-peak currents to
charge/discharge the gate capacitance of external
MOSFETs, or insulated gate bipolar transistors
(IGBTs). In high-frequency switching power supplies,
the Pulse-Width Modulation (PWM) controller may not
have the drive capability to directly drive the power
MOSFET. MOSFET drivers, like the MCP14E6/7/8
family, can be used to provide additional source/sink
current capability.
An additional degree of control has been added to the
MCP14E6/7/8 family. There are seperate enable functions for each driver that allow for the immediate termination of the output pulse, regardless of the state of the
input signal.
4.2
MOSFET Driver Timing
The ability of a MOSFET driver to transition from a fully
OFF state to a fully ON state are characterized by the
drivers’ rise time (tR), fall time (tF) and propagation
delays (tD1 and tD2). The MCP14E6/7/8 family of drivers
can typically charge and discharge a 1000 pF load
capacitance, in approximately 12 ns, along with a typical
matched propagation delay of 45 ns. Figure 4-1 and
Figure 4-2 show the test circuit and timing waveform
used to verify the MCP14E6/7/8 timing.

Non-Inverting Driver Timing
Enable Function
The ENB_A and ENB_B enable pins allow the independent control of OUT A and OUT B, respectively. They
are active-high and are internally pulled up to VDD so
that the default state is to enable the driver. These pins
can be left floating for normal operation.
When an enable pin voltage is above enable pin high
threshold voltage, (VEN_H), that driver output is enabled
and allowed to react to changes in the INPUT pin voltage state. Similarly, when the enable pin voltage falls
below the enable pin low threshold voltage, (VEN_L),
that driver output is disabled and does not respond to
the changes in the INPUT pin voltage state. When the
driver is disabled, the output goes to a low state. Refer
to Table 4-1 for enable pin logic. The threshold voltages
of the enable function are compatible with logic levels.
Hysteresis is provided to help increase the noise immunity of the enable function, avoiding false triggers of the
enable signal during driver switching. For robust
designs, it is recommended that the slew rate of the
enable pin signal be greater than 1V/ns.
There are propagation delays associated with the
driver receiving an enable signal and the output
reacting. These propagation delays, tD3 and tD4, are
graphically represented in Figure 4-3.

PCB Layout Considerations
Proper PCB layout is important in a high-current, fast
switching circuit to provide proper device operation and
robustness to the design. The PCB trace loop area and
inductance should be minimized by the use of ground
planes or trace under MOSFET gate drive signals, separate analog and power grounds, and local driver
decoupling.

Placing a ground plane beneath the MCP14E6/7/8 will
help as a radiated noise shield, as well as providing
some heat sinking for power dissipated within the

Power Dissipation
The total internal power dissipation in a MOSFET driver
is the summation of three separate power dissipation
elements (Figure 4-1).
EQUATION 4-1:
P T = P L + PQ + P CC
4.4
Decoupling Capacitors
Where:
Careful layout and decoupling capacitors are highly
recommended when using MOSFET drivers. Large
currents are required to charge and discharge capacitive loads quickly. For example, approximately 1.8A
are needed to charge a 1000 pF load with 18V in 10 ns.
To operate the MOSFET driver over a wide frequency
range, with low supply impedance, a ceramic and lowESR film capacitors are recommended to be placed in
parallel between the driver, VDD and GND. A 1.0 µF
low-ESR film capacitor and a 0.1 µF ceramic capacitor
placed between pins, 6 and 3, should be used. These
capacitors should be placed close to the driver to minimize the circuit board parasitics and provide a local
source for the required current.

CAPACITIVE LOAD DISSIPATION
The power dissipation caused by a capacitive load is a
direct function of frequency, total capacitive load and
supply voltage. The power lost in the MOSFET driver
for a complete charging and discharging cycle of a
MOSFET is:
EQUATION 4-2:
P L = f × C T × V DD

Where:
f = Switching frequency
CT = Total load capacitance
VDD = MOSFET driver supply voltage

4.6.2
QUIESCENT POWER DISSIPATION
The power dissipation associated with the quiescent
current draw depends upon the state of the input pin.
The MCP14E6/7/8 devices have a quiescent current
draw with a Logic '1' on the input pin of 1 mA (typical)
and 300 µA (typical) with a Logic '0'. The quiescent
power dissipation is:
4.6.3
OPERATING POWER DISSIPATION
The operating power dissipation occurs each time the
MOSFET driver output transitions, because for a very
short period of time, both MOSFETs in the output stage
are ON, simultaneously. This cross-conduction current
leads to a power dissipation described as:
EQUATION 4-4:
EQUATION 4-3:
P Q = ( I QH × D + I QL × ( 1 – D ) ) × V DD
Where:
IQH = Quiescent Current in the High State
D = Duty Cycle
