High-Speed Combi-Sense® Synchronous Power MOSFET Driver for Mobile Applications


Obsolete - this device is no longer available.


  • Combi-Sense dual MOSFET driver
  • High efficiency
  • Shutdown mode for increased power saving
  • Tri-state capability
  • Fast rise and fall times (15 ns typical with 3000 pF load)
  • 5 V gate drive
  • Ultra-low (<20 ns) propagation delay (BG going low)
  • Adaptive and programmable non-overlapping gate drives provide shoot-through protection
  • Floating top drive switches up to 27 V
  • High-frequency operation (to 1.5 MHz) allows use of small inductors and low-cost ceramic capacitors
  • Under-voltage lockout
  • Low quiescent current
  • MLP-12 package provides superior thermal performance in a small footprint


  • High-efficiency portable and notebook computers
  • Battery-powered applications
