TC4421/TC4422 9A High-Speed MOSFET Drivers Features General Description High Peak Output Current: 9A The TC4421/TC4422 are high-current buffer/drivers capable of driving large MOSFETs and IGBTs. Wide Input Supply Voltage Operating Range: - 4.5V to 18V These devices are essentially immune to any form of upset, except direct overvoltage or over-dissipation. High Continuous Output Current: 2A Max They cannot be latched under any conditions within Fast Rise and Fall Times: their power and voltage ratings. These parts are not - 30 ns with 4,700 pF Load subject to damage or improper operation when up to - 180 ns with 47,000 pF Load 5V of ground bounce is present on their ground termi- Short Propagation Delays: 30 ns (typ) nals. They can accept, without damage or logic upset, more than 1A inductive current of either polarity being Low Supply Current: forced back into their outputs. In addition, all terminals - With Logic 1 Input 200 A (typ) are fully protected against up to 4 kV of electrostatic - With Logic 0 Input 55 A (typ) discharge. Low Output Impedance: 1.4 (typ) The TC4421/TC4422 inputs may be driven directly Latch-Up Protected: Will Withstand 1.5A Output from either TTL or CMOS (3V to 18V). In addition, Reverse Current 300 mV of hysteresis is built into the input, providing Input Will Withstand Negative Inputs Up To 5V noise immunity and allowing the device to be driven Pin-Compatible with the TC4420/TC4429 from slowly rising or falling waveforms. 6A MOSFET Driver With both surface-mount and pin-through-hole Space-saving 8-Pin 6x5 DFN Package packages and four operating temperature range offer- ings, the TC4421/22 family of 9A MOSFET drivers fit Applications into most any application where high gate/line capacitance drive is required.
