TC4421M/TC4422M 9A High-Speed MOSFET Drivers Features General Description High Peak Output Current: 9A The TC4421M/TC4422M are high-current buffer/ drivers capable of driving large MOSFETs and IGBTs. Wide Input Supply Voltage Operating Range: - 4.5V to 18V They are essentially immune to any form of upset, except direct overvoltage or over-dissipation. They High Continuous Output Current: 2A Max cannot be latched, under any conditions, within their Fast Rise and Fall Times: power and voltage ratings. These parts are not subject - 30 ns with 4,700 pF Load to damage or improper operation when up to 5V of - 180 ns with 47,000 pF Load ground bounce is present on their ground terminals. Short Propagation Delays: 30 ns (typ) They can accept, without damage or logic upset, more than 1A inductive current of either polarity being forced Low Supply Current: back into their outputs. In addition, all terminals are fully - With Logic 1 Input 200 A (typ) protected against up to 4 kV of electrostatic discharge. - With Logic 0 Input 55 A (typ) The TC4421M/TC4422M inputs may be driven directly Low Output Impedance: 1.4 (typ) from either TTL or CMOS (3V to 18V). In addition, Latch-Up Protected: Will Withstand 1.5A Output 300 mV of hysteresis is built into the input, providing Reverse Current noise immunity and allowing the device to be driven Input: Will Withstand Negative Inputs Up To 5V from slowly rising or falling waveforms.
