MOSFET drivers come in small packages

Microchip has announced what it says is the first in a new family of power MOSFET drivers. Featuring a new driver architecture for high speed operation, the MCP14A005X and MCP14A015X are available in SOT-23 and 2 x 2mm DFN packages. The small packaging enables higher power densities and smaller solutions, while the design targets fast transitions and short delay times that allow for responsive circuit operation.

The MOSFET drivers have a low input threshold compatible with Microchip PIC MCUs and Digital Signal Controllers, even when operating at lower voltages. This enables customers to design applications with MCUs operating as low as 2V, using the MOSFET driver to boost the output signals to 18V, reducing power loss in the controller and minimising conduction loss in the power MOSFET.

The threshold levels balance the need for noise immunity with the ability to function with a wider variety of controller products, including Microchip's devices.

The drivers are designed for use in applications such as power supply, lighting, automotive and consumer electronics.
