Product Summary

The TC4422 are high-current buffer/drivers capable of driving large MOSFETs and IGBTs.These devices are essentially immune to any form ofupset, except direct overvoltage or over-dissipation.They cannot be latched under any conditions withintheir power and voltage ratings. These parts are notsubject to damage or improper operation when up to5V of ground bounce is present on their ground termi-nals. They can accept, without damage or logic upset,more than 1A inductive current of either polarity beingforced back into their outputs. In addition, all terminalsare fully protected against up to 4 kV of electrostaticdischarge

Parametrics

The absolute maximum ratings of TC4422COA are
(1)Supply Voltage :+20V;
(2)Input Voltage: (VDD + 0.3V) to (GND – 5V);
(3)Input Current (VIN > VDD):50 mA;
(4)Package Power Dissipation (TA ≤ 70°C):SOIC: 750 mW
