High-Speed Synchronous Power MOSFET Smart Driver

Add to Watch List

The SC1405D is a Dual-MOSFET Driver with an internal Overlap Protection Circuit to prevent shoot-through. Each driver is capable of driving a 3000pF load in 15ns rise/fall time and has ULTRA-LOW propagation delay from input transition to the gate of the power FETs.


  • Fast rise and fall times (15ns with 3000pf load)
  • 14ns max. Propagation delay (BG going with low)
  • Adaptive and programmable shoot-through         protection
  • Adaptive overvoltage protection
  • Wide input voltage range (4.5V - 25V)
  • Programmable delay between FETs
  • Power saving asynchronous mode control
  • Output overvoltage protection/overtemp shutdown
  • Under-Voltage lock-out and power ready signal
  • Less than 10µA stand-by current (EN=low)
  • Power ready output signal
  • High frequency (to 1.2MHz) operation allows use of small inductors and low cost caps in place of electrolytics
  • TSSOP-14 package


  • High-density/fast-transient microprocessor power supplies
  • Motor drives/class-D amps
  • High-efficiency portable computers
