QUIESCENT POWER DISSIPATION
The power dissipation associated with the quiescent
current draw of the MCP14E3/MCP14E4/MCP14E5
depends upon the state of the input and enable pins.
Refer to the DC Characteristic table for the quiescent
current draw for specific combinations of input and
enable pin states. The quiescent power dissipation is:
EQUATION 4-3:
P Q = ( I QH × D + I QL × ( 1 – D ) ) × V DD
Where:

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 describes as:
EQUATION 4-4:
P CC = CC × f × V DD
