Additional Details

The TC4429 provides a push-pull output stage capable of delivering high peak currents to quickly charge and discharge the gate capacitance of MOSFETs and IGBTs. The low propagation delay ensures that the driver responds quickly to input signals. The over-temperature protection shuts down the driver in case of excessive temperature. The under-voltage lockout prevents the MOSFET from operating with insufficient gate drive voltage, protecting it from damage.
