The TC4423A is a dual-channel inverting high-speed MOSFET driver capable of sourcing and sinking 4.5A peak output current. It operates from a 4.5V to 18V supply voltage and can drive 1800pF loads in 12ns typical rise and fall times, with 40ns typical propagation delay. The device features low quiescent current of 1.0mA maximum with a logic '1' input and 150µA maximum with a logic '0' input, and low output impedance of 2.5Ω typical. It is latch-up protected to withstand 1.5A reverse current and accepts logic inputs down to -5V. Available in 8-pin SOIC and 8-pin 6x5 DFN packages, it is pin-compatible with the TC4423/TC4424/TC4425
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.
