TC4421A/TC4422A  
9A High-Speed MOSFET Drivers  
General Description  
Features  
• High Peak Output Current: 10A (typ.)  
The TC4421A/TC4422A are improved versions of the  
earlier TC4421/TC4422 family of single-output  
MOSFET drivers. These devices are high-current  
buffer/drivers capable of driving large MOSFETs and  
Insulated Gate Bipolar Transistors (IGBTs). The  
TC4421A/TC4422A have matched output rise and fall  
times, as well as matched leading and falling-edge  
propagation delay times. The TC4421A/TC4422A  
devices also have very low cross-conduction current,  
reducing the overall power dissipation of the device.  
• Low Shoot-Through/Cross-Conduction Current in  
Output Stage  
• Wide Input Supply Voltage Operating Range:  
- 4.5V to 18V  
• High Continuous Output Current: 2A (max.)  
• Matched Fast Rise and Fall Times:  
- 15 ns with 4,700 pF Load  
- 135 ns with 47,000 pF Load  
These devices are essentially immune to any form of  
upset, except direct overvoltage or over-dissipation.  
They cannot be latched under any conditions within  
their power and voltage ratings. These parts are not  
subject to damage or improper operation when up to  
5V of ground bounce is present on their ground  
terminals. They can accept, without damage or logic  
upset, more than 1A inductive current of either polarity  
being forced back into their outputs. In addition, all  
terminals are fully protected against up to 4 kV of  
electrostatic discharge.  
• Matched Short Propagation Delays: 42 ns (typ.)  
• Low Supply Current:  
- With Logic ‘1’ Input – 130 µA (typ.)  
- With Logic ‘0’ Input – 33 µA (typ.)  
• Low Output Impedance: 1.2Ω (typ.)  
• Latch-Up Protected: Will Withstand 1.5A Output  
Reverse Current  
• Input Will Withstand Negative Inputs Up To 5V  
• Pin-Compatible with the TC4420/TC4429  
and TC4421/TC4422 MOSFET Drivers  
The TC4421A/TC4422A inputs may be driven directly  
from either TTL or CMOS (3V to 18V). In addition,  
300 mV of hysteresis is built into the input, providing  
noise immunity and allowing the device to be driven  
from slowly rising or falling waveforms.  
• Space-Saving, Thermally-Enhanced, 8-Pin DFN  
Package  
Applications  
• Line Drivers for Extra Heavily-Loaded Lines  
• Pulse Generators  
With both surface-mount and pin-through-hole  
packages, in addition to a wide operating temperature  
range, the TC4421A/TC4422A family of 9A MOSFET  
drivers fit into most any application where high gate/line  
capacitance drive is required.  
• Driving the Largest MOSFETs and IGBTs  
• Local Power ON/OFF Switch  
• Motor and Solenoid Driver  
• LF Initiator
