Compact power MOSFET drivers support high speed operation

Keywords:Microchip Technology  MOSFET driver  MCU  DSC 

Microchip Technology Inc. has rolled out its first power MOSFET drivers that flaunt a unique driver architecture for high speed operation. The MCP14A005X and MCP14A015X, the first in the MCP14A product line, are among the smallest packaged MOSFET drivers on the market, the company stated.

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. Additionally, the MOSFET drivers include low input threshold voltages that are compatible with low voltage MCUs and controllers, while still maintaining strong noise immunity and hysteresis.

MCP14A005X, MCP14A015X

The MCP14A005X and MCP14A015X MOSFET drivers' low input threshold is compatible with various Microchip PIC MCUs and dsPIC DSCs, 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 variety of controller products including Microchip's devices. These drivers are geared for power supply, lighting, automotive and consumer electronics markets, including embedded power conversion, brushed DC motor, unipolar stepper motor and solenoid/relay/valve control applications, among others.

The MCP14A005X and MCP14A015X are available for sampling and volume production in SOT-23 and 2mm x 2mm DFN packages, at prices ranging from $0.50 to $0.61 each, in 10,000-unit quantities.
