TC4451/TC4452 12A High-Speed MOSFET Drivers Features: General Description: High Peak Output Current: 13A (typical) The TC4451/TC4452 are single-output MOSFET drivers. These devices are high-current buffers/drivers Low Shoot-Through/Cross-Conduction Current in capable of driving large MOSFETs and insulated gate Output Stage bipolar transistors (IGBTs). The TC4451/TC4452 have Wide Input Supply Voltage Operating Range: matched output rise and fall times, as well as matched - 4.5V to 18V leading and falling-edge propagation delay times. The High Continuous Output Current: 2.6A TC4451/TC4452 devices also have very low cross- (maximum) conduction current, reducing the overall power Matched Fast Rise and Fall Times: dissipation of the device. - 21 ns with 10,000 pF Load These devices are essentially immune to any form of - 42 ns with 22,000 pF Load upset, except direct overvoltage or over-dissipation. Matched Short Propagation Delays: 44 ns They cannot be latched under any conditions within their power and voltage ratings. These parts are not (typical) subject to damage or improper operation when up to Low Supply Current: 5V of ground bounce is present on their ground - With Logic 1 Input 140 A (typical) terminals. They can accept, without damage or logic - With Logic 0 Input 40 A (typical) upset, more than 1.5A inductive current of either Low Output Impedance: 0.9 (typical) polarity being forced back into their outputs. In addition, Latch-Up Protected: Withstands 1.5A Output all terminals are fully protected against electrostatic Reverse Current discharge (ESD) up to 4.0 kV (HBM) and 400V (MM). Input Withstands Negative Inputs Up To 5V The TC4451/TC4452 inputs may be driven directly Pin-Compatible with the TC4420/TC4429, from either TTL or CMOS (3V to 18V). Moreover, TC4421/TC4422 and TC4421A/TC4422A 300 mV of hysteresis is built into the input, providing MOSFET Drivers noise immunity and enabling the device to be driven from slowly rising or falling waveforms. Space-Saving, Thermally-Enhanced, 8-Pin DFN- S Package With a wide operating temperature range and having both surface-mount and pin-through-hole packages, Applications: the TC4451/TC4452 family of 12A MOSFET drivers fits into any application where high gate/line capacitance Line Drivers for Extra Heavily-Loaded Lines drive is required.
