MOSFET driver's small package improves efficiency
The first in a new product family, Microchip Technology has introduced two power MOSFET drivers in SOT-23 and 2x2mm DFN packages. The MCP14A005X and MCP14A015X are designed for applications including embedded power conversion, brushed DC motor, unipolar stepper motor and solenoid/relay/valve control in power supply, lighting, automotive and consumer electronics markets.
Being among the smallest packaged MOSFET drivers available enables higher power densities and smaller solutions. An entirely new driver architecture for high-speed operation targets fast transitions and short delay times that allow for responsive circuit operation.
The MCP14A005X and MCP14A015X include low input threshold voltages that are compatible with various low voltage Microchip PIC MCUs and dsPIC DSCs, while still maintaining strong noise immunity and hysteresis. Reducing power loss in the controller and minimising conduction loss in the power MOSFET, this facilitates applications with MCUs operating as low as 2.0V, using the MOSFET driver to boost the output signals to 18V.
The MCP14A005X and MCP14A015X are available now for sampling and volume production.
