The MCP1415/16 devices are high-speed, dual
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 or non-inverting single
channel output is directly controlled from either TTL or
CMOS (3V to 18V) logic. These devices also feature
low shoot-through current, matched rise and fall time,
and short propagation delays which make them ideal
for high switching frequency applications. They provide
low enough impedances in both the ‘On’ and ‘Off’
states to ensure the intended state of the MOSFET is
not affected, even by large transients.

•
•
These devices are highly latch-up resistant under any
condition within their power and voltage ratings. They
are not subject to damage when noise spiking (up to
5V, of either polarity) occurs on the Ground pin. 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 2.0 kV (HBM) and
300V (MM).

Ground (GND)
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.
Ground is the device return pin. The ground 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.
3.2
3.4
Control Input (IN)
The MOSFET driver 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.
2008-2016 Microchip Technology Inc.
Output (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.

APPLICATION INFORMATION
4.1
General Information
VDD = 18V
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 MCP1415/16
family can be used to provide additional source/sink
current capability.

The ability of a MOSFET driver to transition from a
fully-off 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
MCP1415/16 timing.

Decoupling Capacitors
Careful 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.
Input

Non-Inverting Driver Timing
10%
To operate the MOSFET driver over a wide frequency
range with low supply impedance, it is recommended to
place a ceramic and a low ESR film capacitor 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 2 and 4 are required for reliable
operation. These capacitors should be placed close to
the driver to minimize circuit board parasitics and
provide a local source for the required current.

Power Dissipation
The total internal power dissipation in a MOSFET driver
is the summation of three separate power dissipation
elements.
EQUATION 4-1:
P T = P L + P Q + P CC
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.

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.

PCB Layout Considerations
Proper 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. PCB trace loop area
and inductance must be minimized. This is
accomplished by placing the MOSFET driver directly at
the load and placing the bypass capacitor directly at the
MOSFET driver (see Figure 4-3). Locating ground
planes or ground return traces directly beneath the
driver output signal reduces trace inductance. A ground
plane also helps as a radiated noise shield and it provides some heat sinking for power dissipated within the
device (see Figure 4-4).
QUIESCENT POWER DISSIPATION
The power dissipation associated with the quiescent
current draw depends on the state of the input pin. The
MCP1415/16 devices have a quiescent current draw of
0.65 mA (typical) when the input is high and of 0.1 mA
(typical) when the input is low. The quiescent power
dissipation is shown in Equation 4-3.
