Power MOSFET drivers in smaller, thermally efficient packages
MCP14A005X and MCP14A015X feature a new driver architecture for high-speed operation, the first in the MCP14A product line. The small packaging enables higher power densities and smaller solutions, while the design targets fast transitions and short delay times. Additionally, these MOSFET drivers include low input threshold voltages that are compatible with low voltage MCUs and controllers, while still maintaining strong noise immunity and hysteresis.
The drivers’ low input threshold is compatible with various Microchip PIC microcontrollers (MCUs) and dsPIC Digital Signal Controllers (DSCs), even when operating at lower voltages, as low as 2.0V; the MOSFET driver boosts 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.
