TC4403  
1.5A HIGH-SPEED, FLOATING LOAD DRIVER  
GENERAL DESCRIPTION  
FEATURES  
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-  
tionallowstheimplementationofawidevarietyofredundant

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.
