TC4421A/TC4422A9A High-Speed MOSFET DriversFeaturesGeneral Description • High Peak Output Current: 10A (typ.) The TC4421A/TC4422A are improved versions of the • Low Shoot-Through/Cross-Conduction Current in earlier TC4421/TC4422 family of single-output Output Stage MOSFET drivers. These devices are high-current buf- • Wide Input Supply Voltage Operating Range: fer/drivers capable of driving large MOSFETs and Insu- lated Gate Bipolar Transistors (IGBTs). The - 4.5V to 18V TC4421A/TC4422A have matched output rise and fall • High Continuous Output Current: 2A (max.) times, as well as matched leading and falling-edge • Matched Fast Rise and Fall Times: propagation delay times. The TC4421A/TC4422A - 15 ns with 4,700 pF Load devices also have very low cross-conduction current, - 135 ns with 47,000 pF Load reducing the overall power dissipation of the device. • Matched Short Propagation Delays: 42 ns (typ.) These devices are essentially immune to any form of • Low Supply Current: upset, except direct overvoltage or over-dissipation. They cannot be latched under any conditions within - With Logic ‘1’ Input – 130 µA (typ.) their power and voltage ratings. These parts are not - With Logic ‘0’ Input – 33 µA (typ.) subject to damage or improper operation when up to • Low Output Impedance: 1.2 (typ.) 5V of ground bounce is present on their ground • Latch-Up Protected: Will Withstand 1.5A Output terminals. They can accept, without damage or logic Reverse Current upset, more than 1A inductive current of either polarity • Input Will Withstand Negative Inputs Up To 5V being forced back into their outputs. In addition, all • Pin-Compatible with the TC4420/TC4429 terminals are fully protected against up to 4 kV of and TC4421/TC4422 MOSFET Drivers electrostatic discharge. • Space-Saving, Thermally-Enhanced, 8-Pin DFN The TC4421A/TC4422A inputs may be driven directly Package from either TTL or CMOS (3V to 18V). In addition, 300 mV of hysteresis is built into the input, providing Applications noise immunity and allowing the device to be driven from slowly rising or falling waveforms. • Line Drivers for Extra Heavily-Loaded Lines With both surface-mount and pin-through-hole • Pulse Generators packages, in addition to a wide operating temperature • Driving the Largest MOSFETs and IGBTs range, the TC4421A/TC4422A family of 9A MOSFET • Local Power ON/OFF Switch drivers fit into most any application where high gate/line • Motor and Solenoid Driver capacitance drive is required. • LF Initiator Package Types(1)8-PinTC4421A TC4422A5-Pin TO-2208-Pin DFN(2) TC4421A TC4422APDIP/SOIC Tab is V V V DD 1 8 VDD VDD Common DD 1 8 VDD DD INPUT 2 7 OUTPUT to V TC4421A 2 DD OUTPUT INPUT 7 TC4421A OUTPUT OUTPUT NC 3 6 OUTPUT TC4422A OUTPUT TC4421A NC 3 TC4422A 6 OUTPUT OUTPUT GND 4 5 GND GND TC4422A GND 4 5 GND GND T Note 1: Duplicate pins must both be connected for proper operation.
