FUNCTIONAL BLOCK DIAGRAM
GENERAL DESCRIPTION
The TC4403 is a modified version of the TC4425 driver,
intended to drive floating or isolated loads requiring high-
current pulses. The load is intended to be connected be-
tween the outputs without other reference to supply or
ground. Then, only when both logic inputs and the VDD input
are energized, is power supplied to the load. This construc-
tion allows the implementation of a wide variety of redundant
input controllers.
The low OFF-state output leakage and independence of
the two half-circuits permit a wide variety of testing schemes
to be utilized to assure functionality. The high peak current
capability, short internal delays, and fast output rise and fall
times ensure that sufficient power will be available to the
load when it is needed. The TTL and CMOS compatible
inputs allow operation from a wide variety of input devices.
The ability to swing the inputs negative without affecting
device performance allows negative biases to be placed on
the inputs for greater safety. In addition, the capacitive
nature of the inputs allows the use of series resistors on the
inputs for extra noise suppression.
The TC4403 is built for outstanding ruggedness and
reliability in harsh applications. Input voltage excursions
above the supply voltage or below ground are clamped
internally without damaging the device. The output stages
are power MOSFETs with high-speed body diodes to pre-
vent damage to the driver from inductive kickbacks.
