资 源 简 介
The TC4403 is a modified version of the TC4425 driver,intended to drive floaTIng or isolated loads requiringhigh-current pulses. The load is intended to be connectedbetween the outputs without other reference tosupply or ground. Then, only when both logic inputsand the VDD input are energized, is power supplied tothe load. This construcTIon allows the implementaTIonof a wide variety of redundant input controllers.The low OFF-state output leakage and independenceof the two half-circuits permit a wide variety of tesTIngschemes to be utilized to assure functionality. The highpeak current capability, short internal delays, and fastoutput rise and fall times ensure that sufficient powerwill be available to the load when it is needed. The TTLand CMOS compatible inputs allow operation from awide variety of input devices. The ability to swing theinputs negative without affecting device performanceallows negative biases to be placed on the inputs forgreater safety. In addition, the capacitive nature of theinputs allows the use of series resistors on the inputsfor extra noise suppression.The TC4403 is built for outstanding ruggedness andreliability in harsh applications. Input voltage excursionsabove the supply voltage or below ground areclamped internally without damaging the device. Theoutput stages are power MOSFETs with high-speedbody diodes to prevent damage to the driver frominductive kickbacks.
