Microchip Technology recently announced the first power MOSFET drivers in a new product family—the MCP14A005X and MCP14A015X. The drivers feature a new driver architecture for high-speed operation.
The new devices’ small packaging (SOT-23 and 2 mm × 2 mm DFN packages) enables higher power densities and smaller solutions, while the design targets fast transitions and short delay times that allow for responsive circuit operation. In addition, the MOSFET drivers include low input threshold voltages that are compatible with low-voltage microcontrollers (MCUs) and controllers, while still maintaining strong noise immunity and hysteresis.
The MCP14A005X and MCP14A015X MOSFET drivers low input threshold is compatible with various Microchip PIC microcontrollers and dsPIC Digital Signal Controllers (DSCs), even when operating at lower voltages. This enables you to design applications with MCUs operating as low as 2 V, using the MOSFET driver to boost the output signals to 18 V, reducing power loss in the controller and minimizing 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. These drivers are designed for use in 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 now for sampling and volume production in SOT-23 and 2 × 2 mm DFN packages. Prices range from $0.50 to $0.61 each in 10,000-unit quantities.
