The MCP1406/07 devices have two pins each for V
OUTPUT, and GND. Both pins must be used for proper
operation. This also lowers path inductance which will,
along with proper decoupling, help minimize ringing in
the circuit.
Placing a ground plane beneath the MCP1406/07 will
help as a radiated noise shield as well as providing
some heat sinking for power dissipated within the
device.
4.5
The total internal power dissipation in a MOSFET driver
is the summation of three separate power dissipation
elements.
4.5.1
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:

The power dissipation associated with the quiescent
current draw depends upon the state of the input pin.
The MCP1406/07 devices have a quiescent current
draw when the input is high of 0.13 mA (typ) and
0.035 mA (typ) when the input is low. The quiescent
power dissipation is:
4.5.3
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 describes as:
