The TC4420 is a 6A (peak), single-output MOSFET driver with a non-inverting design. Fabricated in CMOS, it offers lower power consumption and superior efficiency compared to bipolar drivers. The device features TTL/CMOS compatible inputs that can tolerate voltage swings from VDD + 0.3V to -5V without any risk of damage.
One key advantage of the TC4420 is its rail-to-rail output swing, ensuring optimal drive voltage margin, particularly during power-up and power-down sequences. With a propagational delay time of just 55 ns (typ.) and rise/fall times of 25 ns (typ.) into 2500 pF, it offers fast and efficient operation within the usable power supply range.
Notably, the TC4420 boasts virtually latch-up proof capabilities, eliminating the need for multiple discrete components. This not only saves PCB space but also enhances overall system reliability. The device comes in space-saving 8-pin SOIC and 8-pin 6x5 DFN packages.
