TC4427AEUA Generic

TC4426A/TC4427A/TC4428A 1.5A Dual High-Speed Power MOSFET Drivers Features: General Description: High Peak Output Current 1.5A The TC4426A/TC4427A/TC4428A are improved versions of the earlier TC4426/TC4427/TC4428 family Wide Input Supply Voltage Operating Range: of MOSFET drivers. In addition to matched rise and fall - 4.5V to 18V times, the TC4426A/TC4427A/TC4428A devices have High Capacitive Load Drive Capability 1000 pF matched leading and falling edge propagation delay in 25 ns (typ.) times. Short Delay Times 30 ns (typ.) These devices are highly latch-up resistant under any Matched Rise, Fall and Delay Times conditions within their power and voltage ratings. They Low Supply Current: are not subject to damage when up to 5V of noise - With Logic 1 Input 1 mA (typ.) spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, up to - With Logic 0 Input 100 A (typ.) 500 mA of reverse current (of either polarity) being Low Output Impedance 7 (typ.) forced back into their outputs. All terminals are fully Latch-Up Protected: Will Withstand 0.5A Reverse protected against Electrostatic Discharge (ESD) up to Current 4kV. Input Will Withstand Negative Inputs Up to 5V The TC4426A/TC4427A/TC4428A MOSFET drivers ESD Protected 4 kV can easily charge/discharge 1000pF gate Pin-compatible with TC426/TC427/TC428 and capacitances in under 30 ns. These devices provide TC4426/TC4427/TC4428 low enough impedances in both the on and off states to Space-saving 8-Pin MSOP and 8-Pin 6x5 DFN ensure the MOSFETs intended state will not be Packages affected, even by large transients.
