The TC4426A is a 1.5A dual inverting high-speed MOSFET driver designed for switch mode power supplies, line drivers, and pulse transformer drive applications. It operates from a 4.5V to 18V supply voltage and delivers a typical peak output current of 1.5A with a low output impedance of 7Ω. The device can drive a 1000pF capacitive load in 25ns (typical) and has a typical propagation delay of 30ns. It features matched rise, fall, and delay times, input immunity to negative voltages up to 5V, and latch-up protection withstanding up to 0.5A reverse current. All terminals are ESD protected up to 2kV. The TC4426A is available in 8-pin MSOP and 8-pin 6x5 DFN-S packages with an exposed thermal pad.
The TC4426A/4427A/4428A are improved versions of the earlier TC426/427/428 family of buffer/drivers (with which they are pin compatible). They will not latch up 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 500mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against up to 4kV of electrostatic discharge. As MOSFET drivers, the TC4426A/4427A/4428A can easily switch 1000pF gate capacitances in under 30nsec, and 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.
