IR Introduces IRS44273L Compact Low-Side Gate Drive IC in SOT-23-5L Package

EL SEGUNDO, Calif.--(BUSINESS WIRE)-- International Rectifier, IR® (NYS: IRF) , a world leader in power management technology, today introduced the IRS44273L low-side gate drive IC offering high drive capability in a highly compact SOT-23-5L package.

The IRS44273L is easy to use and provides a simple solution for IGBT and MOSFET gate drive, offering 1.5A (typical) sink and source capability, fast switching performance and integrated under-voltage lockout protection with minimal board space requirements. This new device offers functionality previously only available in larger packages such as an SO-8, enabling more compact and economical system design.

"The new IRS44273L offers the highest available drive current for a low-side driver in an SOT-23-5L package enabling designers to use it in place of larger SO-8 devices to significantly reduce solution size," said Tom Ribarich, Director of Lighting Systems and Applications, Energy Savings Products Business Unit.

The IRS44273L has two output pins on either side of the package to simplify system design by offering layout flexibility. The device has non-inverted inputs and is compatible with CMOS and LSTTL controllers.
