TC4420/TC4429 6A High-Speed MOSFET Drivers Features • Latch-Up Protected: Will Withstand >1.5A Reverse Output Current • Logic Input Will Withstand Negative Swing Up To 5V • ESD Protected: 4 kV • Matched Rise and Fall Times: - 25 ns (2500 pF load) • High Peak Output Current: 6A • Wide Input Supply Voltage Operating Range: - 4.5V to 18V • High Capacitive Load Drive Capability: 10,000 pF • Short Delay Time: 55 ns (typ.) • CMOS/TTL Compatible Input • Low Supply Current With Logic ‘1’ Input: - 450 µA (typ.) • Low Output Impedance: 2.5Ω • Output Voltage Swing to Within 25 mV of Ground or VDD • Space-Saving 8-Pin SOIC and 8-Pin 6x5 DFN Packages General Description The TC4420/TC4429 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 and more efficient operation versus bipolar drivers. Both devices have TTL/CMOS compatible inputs that 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 55 ns (typ.) and the output rise and fall times are only 25 ns (typ.) into 2500 pF across the usable power supply range. Unlike other drivers, the TC4420/TC4429 are virtually latch-up proof. They replace three or more discrete components, saving PCB area, parts and improving overall system reliability.

The VDD input should be bypassed to ground with a local ceramic capacitor. The value of the capacitor should be chosen based on the capacitive load that is being driven. A minimum value of 1.0 µF is suggested. The MOSFET driver output is a low-impedance, CMOS, push-pull style output capable of driving a capacitive load with 6.0A peak currents. The MOSFET driver output is capable of withstanding 1.5A peak reverse currents of either polarity. 3.4 3.2 Control Input The MOSFET driver input is a high-impedance, TTL/CMOS compatible input. The input circuitry of the TC4420/TC4429 MOSFET driver also has a “speedup” capacitor. This helps to decrease the propagation delay times of the driver. Because of this, input signals with slow rising or falling edges should not be used, as this can result in double-pulsing of the MOSFET driver output. Ground The ground pins are the return path for the bias current and the high peak currents that discharge the load capacitor. The ground pins should be tied into a ground plane or have very short traces to the bias supply source return. 3.5 Exposed Metal Pad The exposed metal pad of the 6x5 DFN package is not internally connected to any potential. Therefore, this pad can be connected to a ground plane or other copper plane on a printed circuit board (PCB) to aid in heat removal from the package.
