The TC4421 is a high-speed inverting MOSFET driver capable of delivering a peak output current of 9A and a continuous output current of up to 2A. It operates within a supply voltage range of 4.5V to 18V and features fast rise and fall times of 30ns and 180ns, respectively, with specified load capacitances. The device has short propagation delays of approximately 30ns and low output impedance of 1.4Oc, making it suitable for driving large MOSFETs and IGBTs in various applications. It is designed to withstand ground bounce of up to 5V without damage and can handle reverse currents exceeding 1.5A. The TC4421 is compatible with TTL and CMOS logic levels, providing built-in hysteresis for improved noise immunity. It is available in a compact 8-pin DFN-S package, making it suitable for space-constrained designs.
The TC4421/4422 are high current buffer/drivers capable of driving large MOSFETs and IGBTs. They are essentially immune to any form of upset except direct overvoltage or over-dissipation. They cannot be latched under any conditions within their power and voltage ratings; they are not subject to damage or improper operation when up to 5V of ground bounce is present on their ground terminals; they can accept, without either damage or logic upset, more than 1A inductive current of either polarity being forced back into their outputs. In addition, all terminals are fully protected against up to 4kV of electrostatic discharge. The TC4421/4422 inputs may be driven directly from either TTL or CMOS (3V to 18V). In addition, 300mV of hysteresis is built into the input, providing noise immunity and allowing the device to be driven from slowly rising or falling waveforms.
