Microchip Tech Announces 1.5A MOSFET Drivers In SOT-23 Package

July 16, 2008 by Jeff Shepard

Microchip Technology Inc. announced the MCP1415 and MCP1416 (MCP141X) single-output MOSFET drivers. The inverting MCP1415 and non-inverting MCP1416 MOSFET drivers are rated for a peak output current of 1.5A, over a wide operating voltage range of 4.5V – 18V. Both devices are said to have excellent latch-up immunity and are available in a miniature 5-pin SOT-23 package.

Because of their small package size, designers can position the MCP141X MOSFET gate driver close to the MOSFET’s physical gate connection, which minimizes gate bounce caused by the parasitic PCB layout. This also minimizes gate rise-and-fall times, propagation-delay times and shoot-through current, all of which are said to help increase system efficiency and reduce power dissipation.

"Today’s designers are constantly working to build smaller, more efficient designs," said Bryan Liddiard, Vice President of Marketing with Microchip’s Analog & Interface Products Division. "The MCP141X MOSFET drivers were designed to meet these needs, and to provide the robustness and latch-up immunity required for modern switching applications."

"Microchip is pleased to expand its MOSFET driver family into the high output current, small-package segment with the MCP141X devices," said Ray DiSilvestro, Product-Line Marketing Manager with Microchip’s Analog and Interface Products Division. "These drivers complement market trends toward products that enable greater efficiency in smaller packages."

The MCP141X MOSFET drivers are well-suited for a variety of consumer electronic, industrial and medical applications that use power supplies. Examples include personal computers (PCs), laptops, portable measurement devices and centrifuges, among others.

Both the MCP1415 and MCP1416 MOSFET drivers are available in a 5-pin SOT-23 package, for $0.44 each in 10,000-unit quantities.
