General Description
The MCP1401/02 are high-speed MOSFET drivers
capable of providing 500 mA of peak current. The
inverting or non-inverting single channel output is
directly controlled from either TTL or CMOS (3V to
18V). These devices also feature low shoot-through
current, matched rise/fall times and propagation delays
which make them ideal for high switching frequency
applications.
The MCP1401/02 devices operate from a single 4.5V
to 18V power supply and can easily charge and
discharge 470 pF gate capacitance in under 19 ns
(typical). They provide low enough impedances in both
the On and Off states to ensure the MOSFET’s
intended state will not be affected, even by large
transients.
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
500 mA of reverse current being forced back into their
outputs. All terminals are fully protected against
Electrostatic Discharge (ESD) up to 1 kV (HBM) and
300V (MM).
