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.
