The TC4423A is a dual, inverting 3A MOSFET driver designed for high-speed switching applications such as switch-mode power supplies and DC motor drive. It is available in 8-pin PDIP, 8-pin SOIC, and 8-pin 6x5 DFN packages, with the DFN offering enhanced power dissipation. The device operates from a 4.5V to 18V supply, delivers peak output currents of 4.5A, and drives 1800pF loads in 12ns typical rise and fall times. It features matched propagation delay times of 40ns, low quiescent current (1.0mA max at logic '1', 150εA max at logic '0'), and 2.5Ω output impedance. The input accepts TTL/CMOS levels up to 18V with 300mV hysteresis and withstands negative swings to -5V. The device is latch-up protected against 1.5A reverse current and operates over a -40°C to +125°C temperature range.
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.
