The TC4425A is a dual-output 3A MOSFET driver with one inverting and one non-inverting channel, designed for driving power MOSFETs and IGBTs in switch-mode power supplies and similar applications. It operates from a 4.5V to 18V supply, delivers a typical peak output current of 4.5A, and can drive a 1800pF load in 12ns with matched rise and fall times. Propagation delay is 40ns typical, and output impedance is 2.5Ω typical. The device features latch-up protection, withstands up to 5V negative input swing, and consumes 1.0mA maximum with a logic '1' input and 150µA maximum with a logic '0' input. It is available in 8-pin SOIC and 8-pin 6x5 DFN packages, with an operational temperature range of -40°C to +125°C.
The TC4423A/4424A/4425A are a family of dual, 3A-output MOSFET Drivers, which are high-current buffer/drivers capable of driving large MOSFET transistors and Insulated Gate Bipolar Transistors (IGBT).The TC4423A/4424A/4425A have matched leading and falling-edge propagation delay times and have very low cross-conduction currents that help minimize the overall power dissipation of these devices. This family is an improved version of the earlier TC4423/4424/4425 driver family. The new family features higher peak output current drive capability, matched rise/fall times and propagation delay times. An 8-pin SOIC package option has been added to the family, and the 8-pin DFN package option offers increased power dissipation capability for driving heavier capacitive or resistive loads.
