The TC4451 is a single-output, inverting high-speed MOSFET driver designed to drive large MOSFETs and IGBTs with a peak output current of 13A (typical) and a continuous output current of 2.6A (maximum). It operates over a supply voltage range of 4.5V to 18V and features matched rise and fall times of 21ns with a 10,000pF load and 42ns with a 22,000pF load, along with a typical propagation delay of 44ns. The device has a typical output impedance of 0.9Ω, low input supply current, and built-in 300mV hysteresis for noise immunity. It is latch-up protected and withstands 1.5A reverse current. Available in an 8-pin DFN-S package measuring 6x5x0.9mm, with an exposed thermal pad electrically isolated from the circuit.
The TC4451/52 are single-output MOSFET Drivers, which are high-current buffer/drivers capable of driving large MOSFETs and Insulated Gate Bipolar Transisitors (IGBT). Their high drive current of over 12A is capable of driving some of largest power transistors in use today. The TC4451/2 have matched leading and falling-edge propogation delay times and have very low cross-conduction current to minimize the overall power dissipation of the device. They will not latch up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, more than 1500 mA of reverse current (of either polarity) being forced back into their outputs. Additionally, all terminals are fully protected against up to 4kV of electrostatic discharge.
