Looking to drive large power MOSFETs using low voltage controllers?

The new architecture introduced by Microchip’s MCP14A005X and MCP14A015X power MOSFET drivers enables fast transitions of large capacitive loads and wider compatibility with low-voltage MCUs and Digital Signal Controllers (DSCs) combined with a small footprint for higher power density.         

With their thermally-efficient SOT-23 and 2 x 2 mm DFN packages, Microchip’s MCP14A005X and MCP14A015X are among the industry’s smallest MOSFET drivers. The small footprint allows these drivers to be mounted close to the power MOSFET for increased transition speeds as well as enhanced immunity to noise and EMI.

Designed for compatibility with a wide range of microcontrollers and DSCs, these drivers feature input threshold voltages as low as 2.0V and can boost output signals up to 18V. In addition, they reduce power loss in the controller and conduction loss in the power MOSFET.

The new driver architecture provides high-speed operation with fast transitions and short delay times for more responsive operation. This balances the critical need for higher speed and smaller size for many applications.

Key facts:          

  • 2.0V input voltage thresholds compatible with low-voltage MCUs & DSCs
  • Faster MOSFET transitions with enhanced noise immunity
  • Small, thermally-efficient packages for increased power density
