The TC4420 is a 6A peak, non-inverting, single-output CMOS MOSFET driver designed for high-speed switching applications. It operates from a 4.5V to 18V supply voltage and features TTL/CMOS compatible inputs that tolerate negative swings down to -5V. The driver delivers matched rise and fall times of 25ns into a 2500pF load and has a typical propagation delay of 55ns. It provides rail-to-rail output swing, sourcing and sinking 6A peak current with an output impedance of 2.5Ω, and withstands reverse output currents exceeding 1.5A. The device is available in 8-pin SOIC and 8-pin 6x5 DFN packages, with an exposed pad on the DFN for thermal management. It is latch-up protected and operates over temperature ranges up to +125°C for the E and V grades.
The TC4420/4429 are 6A (peak),single output MOSFET drivers. The TC4429 is an inverting driver (pin-compatible with the TC429), while the TC4420 is a non-inverting driver. These drivers are fabricated in CMOS for lower power, more efficient operation versus bipolar drivers. Both devices have TTL-compatible inputs, which can be driven as high as VDD + 0.3V or as low as – 5V without upset or damage to the device. This eliminates the need for external level shifting circuitry and its associated cost and size. The output swing is rail-to-rail ensuring better drive voltage margin, especially during power up/power down sequencing. Propagational delay time is only 55nsec (typ.) and the output rise and fall times are only 25nsec (typ.) into 2500pF across the usable power supply range. Unlike other drivers, the TC4420/4429 are virtually latch-up proof. They replace three or more discrete components saving PCB area, parts and improving overall system reliability.
