TC4421AVOA General Description

The TC4421A/TC4422A are improved versions of the earlier TC4421/TC4422 family of single-output MOSFET gate drivers. These devices are high-current buffer/drivers capable of driving large MOSFETs and Insulated Gate Bipolar Transistors (IGBTs). The TC4421A/TC4422A have matched output rise and fall times, as well as matched leading and falling-edge propagation delay times. The TC4421A/TC4422A devices also have very low cross-conduction current, reducing the overall power dissipation of the device.

These devices 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. These parts are not subject to damage or improper operation when up to 5 V of ground bounce is present on their ground terminals. They can accept, without damage or logic upset, more than 1 A inductive current of either polarity being forced back into their outputs. In addition, all terminals are fully protected against up to 4 kV of electrostatic discharge.

The TC4421A/TC4422A inputs may be driven directly from either TTL or CMOS (3 V to 18 V). In addition, 300 mV of hysteresis is built into the input, providing noise immunity and allowing the device to be driven from slowly rising or falling waveforms. With both surface-mount and pin-through-hole packages, in addition to a wide operating temperature range, the TC4421A/TC4422A family of 9 A MOSFET drivers fit into most any application where high gate/line capacitance drive is required
