TC4403

1.5A High-Speed, Floating Load Driver

Features

General Description

• Low Quiescent Current: 300A Max

• Capacitive Inputs With 300mV Hysteresis

• Both Inputs Must Be Driven to Drive Load

• Low Output Leakage

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 con-

nected between the outputs without other reference to

supply or ground. Then, only when both logic inputs

and the V_DDinput are energized, is power supplied to

the load. This construction allows the implementation

of a wide variety of redundant input controllers.

• High Peak Current Capability

• Fast Output Rise Time

• Outputs Individually Testable

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.

Applications

• Isolated Load Drivers

• Pulsers

• Safety Interlocks

The TC4403 is built for outstanding ruggedness and

reliability in harsh applications. Input voltage excur-

sions 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 prevent damage to the driver from

inductive kickbacks.
