TF0227-TAH

Advance Info TF0227(1/2/3/5) Dual High Speed Low-Side Gate Driver Description Features  E  fficient, low-cost solution for driving MOSFETs and IGBTs  Wide supply voltage operating range: 4.5V to 18V  A wide range (1.5A-4A) of source/sink output current capability offerings  Fast propagation delays (35ns typical)  Fast rise and fall times  Logic input (IN) 3.3V capability  Extended temperature range: -40°C to +125°C The TF0227(x), dual, high speed, low side MOSFET and IGBT drivers are capable of driving a range of source/ sink peak capabilities. The TF0227(x) logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with MCUs. Fast and well matched propagation delays allow high speed operation, enabling a smaller, more compact power switching design using smaller associated components. The TF0227(x) is offered in an SOIC-8(N) package and it operates over an extended -40 °C to +125 °C temperature range.
