The MCP14A0151/2 devices are high-speed MOSFET
drivers that are capable of providing up to 1.5A of peak
current while operating from a single 4.5V to 18V
supply. The inverting (MCP14A0151) or non-inverting
(MCP14A0152) single channel output is directly
controlled from either TTL or CMOS (2V to 18V) logic.
These devices also feature low shoot-through current,
matched rise and fall times, and short propagation
delays which make them ideal for high switching
frequency applications.

The MCP14A0151/2 family of devices offer enhanced
control with Enable functionality. The active-high
Enable pin can be driven low to drive the output of the
MCP14A0151/2 low, regardless of the status of the
Input pin. An integrated pull-up resistor allows the user
to leave the Enable pin floating for standard operation.
Additionally, the MCP14A0151/2 devices feature separate ground pins (AGND and GND), allowing greater
noise isolation between the level-sensitive Input/
Enable pins and the fast, high-current transitions of the
push-pull output stage.
These devices are highly latch-up resistant under any
condition within their power and voltage ratings. They
can accept up to 500 mA of reverse current being
forced back into their outputs without damage or logic
upset. All terminals are fully protected against
electrostatic discharge (ESD) up to 1.75 kV (HBM) and
200V (MM).

Exposed Thermal Pad (GND)
Output Pin (OUT, OUT)
The Output is a CMOS push-pull output that is capable
of sourcing and sinking 1.5A of peak current
(VDD = 18V). The low output impedance ensures the
gate of the external MOSFET stays in the intended
state even during large transients. This output also has
a reverse current latch-up rating of 500 mA.
3.5
The MOSFET driver Control Input is a high-impedance,
TTL/CMOS compatible input. The Input also has
hysteresis between the high and low input levels,
allowing them to be driven from slow rising and falling
signals and to provide noise immunity.
3.6
3.2
Power Ground Pin (GND)
GND is the device return pin for the output stage. The
GND pin should have a low-impedance connection to
the bias supply source return. When the capacitive load
is being discharged, high peak currents will flow out of
the ground pin.
Device Enable Pin (EN)
The MOSFET driver Device Enable is a highimpedance, TTL/CMOS compatible input. The Enable
input also has hysteresis between the high and low
input levels, allowing them to be driven from slow rising
and falling signals and to provide noise immunity.
Driving the Enable pin below the threshold will disable
the output of the device, pulling OUT/OUT low,
regardless of the status of the Input pin. Driving the
Enable pin above the threshold allows normal
operation of the OUT/OUT pin based on the status of
the Input pin. The Enable pin utilizes an internal pull up
resistor, allowing the pin to be left floating for standard
driver operation.
3.4
Supply Input Pin (VDD)
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 capacitor. This bypass
capacitor provides a localized low-impedance path for
the peak currents that are provided to the load
3.7
3.3
Control Input Pin (IN)
Exposed Metal Pad Pin (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.
Analog Ground Pin (AGND)
AGND is the device return pin for the input and enable
stages of the MOSFET driver. The AGND pin should be
connected to an electrically “quiet” ground node to provide a low noise reference for the input and enable
pins.

APPLICATION INFORMATION
VDD = 18V
4.1
General Information
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. A MOSFET driver such as the
MCP14A0151/2 family can be used to provide additional source/sink current capability.
4.2
Input
The ability of a MOSFET driver to transition from a fullyoff state to a fully-on state is characterized by the
driver’s rise time (tR), fall time (tF) and propagation
delays (tD1 and tD2). Figure 4-1 and Figure 4-2 show
the test circuit and timing waveform used to verify the
MCP14A0151/2 timing.

Enable Function
The enable pin (EN) provides additional control of the
output pin (OUT). This pin is active high and is internally pulled up to VDD so that the pin can be left floating
to provide standard MOSFET driver operation.
When the enable pin’s voltage is above the enable pin
high voltage threshold, (VEN_H), the output is enabled
and allowed to react to the status of the Input pin.
However, when the voltage applied to the Enable pin
falls below the low threshold voltage (VEN_L), the driver
output is disabled and doesn't respond to changes in
the status of the Input pin. When the driver is disabled,
the output is pulled down to a low state. Refer to
Table 4-1 for enable pin logic. The threshold voltage
levels for the Enable pin are similar to the threshold
voltage levels of the Input pin, and are TTL and CMOS
compatible. Hysteresis is provided to help increase the
noise immunity of the enable function, avoiding false
triggers of the enable signal during driver switching.
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.

Power Dissipation
The total internal power dissipation in a MOSFET driver
is the summation of three separate power dissipation
elements, as shown in Equation 4-1.

Decoupling Capacitors
Careful PCB layout and decoupling capacitors are
required when using power MOSFET drivers. Large
current is required to charge and discharge capacitive
loads quickly. For example, approximately 720 mA are
needed to charge a 1000 pF load with 18V in 25 ns.
To operate the MOSFET driver over a wide frequency
range with low supply impedance, it is recommended to
place 1.0 µF and 0.1 µF low ESR ceramic capacitors in
parallel between the driver VDD and GND. These
capacitors should be placed close to the driver to
minimize circuit board parasitics and provide a local
source for the required current.

PCB Layout Considerations
Proper Printed Circuit Board (PCB) layout is important
in high-current, fast switching circuits to provide proper
device operation and robustness of design. Improper
component placement may cause errant switching,
excessive voltage ringing or circuit latch-up. The PCB
trace loop length and inductance should be minimized
by the use of ground planes or traces under the
MOSFET gate drive signal, separate analog and power
grounds, and local driver decoupling.
Placing a ground plane beneath the MCP14A0151/2
devices will help as a radiated noise shield, as well as
providing some heat sinking for power dissipated within
the device.
 2014 Microchip Technology Inc.
CAPACITIVE LOAD DISSIPATION
The power dissipation caused by a capacitive load is a
direct function of the 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 shown in Equation 4-2.

QUIESCENT POWER DISSIPATION
The power dissipation associated with the quiescent
current draw depends on the state of the Input and
Enable pins. See Section 1.0 “Electrical Characteristics” for typical quiescent current draw values in different operating states. The quiescent power
dissipation is shown in Equation 4-3.

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 in Equation 4-4.
