General Description

The TC4451/TC4452 are single-output MOSFET drivers. These devices are high-current buffer/drivers capable of driving large MOSFETs and Insulated Gate Bipolar Transistors (IGBTs). The TC4451/TC4452 have matched output rise and fall times, as well as matched leading and falling-edge propagation delay times. The TC4451/TC4452 devices also have very low cross conduction current, reducing the overall power dissipation of the device.
