Tài liệu Robot: 3A Dual High-Speed Power MOSFET Drivers TC4423A/TC4424A/TC4425A 3A Dual High-Speed Power MOSFET DriversFeatures General Description• High Peak Output Current: 4.5A (typical) The TC4423A/TC4424A/TC4425A devices are a family• Wide Input Supply Voltage Operating Range: of dual-output 3A buffers/MOSFET drivers. These - 4.5V to 18V devices are improved versions of the earlier TC4423/ TC4424/TC4425 dual-output 3A driver family. This• High Capacitive Load Drive Capability: improved version features higher peak output current - 1800 pF in 12 ns drive capability, lower shoot-throught current, matched• Short Delay Times: 40 ns (typical) rise/fall times and propagation delay times. The• Matched Rise/Fall Times TC4423A/TC4424A/TC4425A devices are pin-• Low Supply Current: compatible with the existing TC4423/TC4424/TC4425 family. An 8-pin SOIC package option has been added - With Logic ‘1’ Input – 1.0 mA (maximum) to the family. The 8-pin DFN package option offers - With Logic ‘0’ Input – 150 µA (maximum) increased power dissipation capability for driving• Low Output Impedance: 2.5Ω (typical) heavier capacitive or resistive loads.• Latch-Up Protected: Will Withstand 1.5A Reverse The TC4423A/TC4424A/TC4425A MOSFET drivers Current can easily charge and discharge 1800 pF gate• Logic Input Will Withstand Negative Swing Up To capacitance in under 20 ns, provide low enough 5V impedances in both the on and off states to ensure the• Pin compatible with the TC4423/TC4424/TC4425 MOSFET’s intended state will not be affected, even by and TC4426A/TC4427A/TC4428A devices large transients.• Space-saving 8-Pin 150 mil body SOIC and 8-Pin The TC4423A/TC4424A/TC4425A inputs may be 6x5 DFN Packages driven directly from either TTL or CMOS (2.4V to 18V). In addition, the 300 mV of built-in hysteresis providesApplications noise immunity and allows the device to be driven from slow rising or falling waveforms.• Switch Mode Power Supplies The TC4423A/TC4424A/TC4425A dual-output 3A• Pulse Transformer Drive MOSFET driver family is offerd with a -40oC to +125oC• Line Drivers temperature rating, making it useful in any wide• Direct Drive of Small DC Motors temperature range application.Package Types 8-Pin PDIP/SOIC TC4423A TC4424A TC4425A 16-Pin SOIC (Wide) TC4423A TC4424A TC4425A NC 1 8 NC NC NC NC 1 16 NC NC NC IN A 2 TC4423A 7 OUT A OUT A OUT A IN A 2 15 OUT A OUT A OUT A GND 3 TC4424A 6 VDD VDD VDD NC 3 14 OUT A OUT A OUT A TC4423A IN B 4 TC4425A 5 OUT B OUT B OUT B GND 4 TC4424A 13 VDD VDD VDD GND 5 TC4425A 12 VDD VDD VDD NC 6 11 OUT B OUT B OUT B 8-Pin 6x5 DFN (1) TC4423A TC4424A TC4425A IN B 7 10 OUT B OUT B OUT B NC ...
