International Rectifier recently debut a compact replacement for larger SO-8 devices. IR's IRS44273L low-side MOSFET and IGBT gate driver can sink and source 1.5A typical from a 5-lead SOT-23 package. The non-inverting driver has two output pins on either side of the package for layout flexibility, and it is compatible with CMOS and LSTTL controllers.

The non-inverting driver has two output pins on either side of the package for layout flexibility, and it is compatible with CMOS and LSTTL controllers.

The IRS44273L provides turn-on and turn-off propagation delay times of 50 ns typical and turn-on rise and fall times of 25ns typical. It operates from a fixed supply voltage of -0.3V to 25V and has an ambient temperature range of -40°C to 125°C. The driver features a current buffer stage, under-voltage lockout, and an output that is in phase with the input.
