The new devices, supplied in 2 x 2 mm SOT-23 and DFN packages, are among the smallest MOSFET drivers currently available. Their small package size allows for higher power densities and smaller footprints, while the design focuses on fast transitions and short delay times, enhancing circuit responsiveness. Furthermore, these MOSFET drivers feature low input threshold voltages, making them compatible with microcontrollers and low-voltage controllers, while maintaining strong noise and hysteresis immunity.
The low input threshold of the MCP14A005X and MCP14A015X MOSFET drivers is compatible with various Microchip PIC® microcontrollers and dsPIC® digital signal controllers (DSCs), even when operating at lower voltages. This allows customers to design microcontroller applications operating at voltages as low as 2.0V, using the MOSFET driver to boost output signals up to 18V, while also reducing power losses in the driver and minimizing conduction losses in the power MOSFET. Threshold levels balance the need for noise immunity with the ability to work with a wider range of driver products, including Microchip devices. These are designed for use in the power supply, lighting, automotive, and consumer electronics markets, including embedded power conversion, brushed DC motors, unipolar stepper motors, and solenoid/relay/valve control applications, among others.
The MCP14A005X and MCP14A015X are available for sampling and volume production in 2 x 2 mm SOT-23 and DFN packages.
