MICROCHIP TC4422AVOA

Line drivers for very large load lines; pulse generators; driving high-power MOSFETs and IGBTs; local power switching; motor and solenoid drivers; LF starters. These devices are high-current buffers/drivers capable of driving high-power MOSFETs or IGBTs. In addition to matched output rise and fall times, they feature matched rise and fall propagation delays. They also exhibit extremely low cross-conduction current, reducing total power dissipation. These devices are essentially immune to all forms of interference unless subjected to direct overvoltage or excessive power dissipation. They are latch-up free under any conditions within their power and voltage ratings. These devices will not be damaged or cause false triggering when ground bounce at the ground pin is ≤5V. They can also withstand inductive currents greater than 1A of either polarity forced back into the output without causing device damage or logic upset. In addition, all pins are fully protected against ESD up to 4kV. The inputs can be driven directly by TTL or CMOS (3V to 18V). Furthermore, the inputs feature 300mV of hysteresis to prevent noise interference and allow slowly rising or falling waveforms to drive the devices. Available in both SMT and through-hole package styles with a wide operating temperature range, suitable for most applications requiring high capacitive drive capability for gates/lines.
