By positioning the tiny gate driver close to the MOSFET’s physical gate connection, designers can minimise gate bounce caused by the parasitic PCB layout, gate rise-and-fall times, propagation-delay times and shoot-through current, all of which help to increase system efficiency and reduce power dissipation.
For higher peak output-current applications, Microchip offers the 4.5A MCP1403/4/5 dual and 6A MCP1406/7 MOSFET drivers. The MCP1403/4/5 devices are available in 8- and 16-pin SOIC and PDIP packages, as well as a 6 x 5 mm DFN package, while the MCP1406/7 drivers are available in 8-pin SOIC, PDIP and 6 mm x 5 mm DFN packages, as well as a 5-pin TO220 package.
