500 mA single-output MOSFET drivers

19 September 2007 Power Electronics / Power Management

Microchip has released the MCP1401 and MCP1402 (MCP140X) single-output MOSFET drivers. The inverting MCP1401 and non-inverting MCP1402 are rated for a peak output current of 0,5 A, over a wide operating voltage range of 4,5 to 18 V. They have excellent latch-up immunity and are available in miniature, 2 x 3 mm DFN and 5-pin SOT-23 packages. 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 4,5 A MCP1403/4/5 dual and 6 A 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.
