MOSFET Drivers and Controllers

MOSFET driver ICs are used to drive external MOSFETs in power supply and motor driver applications. Typically architected in a bridge configuration, MOSFET drivers provide the timing needed to ensure that only one MOSFET is conducting at a time.

ORing MOSFET controllers drive high-power MOSFETs to replace ORing diodes in high-reliability, redundant, parallel-connected power supplies. Because MOSFETs have much lower on-resistance than ORing Schottky diodes, their use results in lower power dissipation, smaller size, and elimination of heatsinks in high-power applications. ORing MOSFET controllers provide the control logic necessary to drive the power MOSFETs.

MOSFET drivers are used in a wide variety of applications, from motor drivers and load switching to switching power supplies. Single and dual drivers, along with secondary-side synchronous drivers, are available for increased efficiency in isolated designs. Evaluation kits are available for quick prototyping and design verification. Industry leading features include:

  • Fast Delay Times
  • High Efficiency
  • High Reliability
  • Small Packages
