MCP14E3/MCP14E4/MCP14E5
4.0A Dual High-Speed Power MOSFET Drivers With Enable
Features General Description
High Peak Output Current: 4.0A (typical) The MCP14E3/MCP14E4/MCP14E5 devices are a
family of 4.0A buffers/MOSFET drivers. Dual-inverting,
Independent Enable Function for Each Driver
dual-noninvertering, and complementary outputs are

standard logic options offered.
Low Shoot-Through/Cross-Conduction Current in
Output Stage The MCP14E3/MCP14E4/MCP14E5 drivers are
capable of operating from a 4.5V to 18V single power
Wide Input Supply Voltage Operating Range:

Motor and Solenoid Drive
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.
They can accept, without damage or logic upset, up to
1.5A of reverse current being forced back into their
outputs. All terminals are fully protect against
Electrostatic Discharge (ESD) up to 4 kV.
