Low-side drivers simplify design and increase performance

Automotive applications using power MOSFETs require gate drivers with high peak drive current and low output impedance. TheFAN31xx_F085and FAN32xx_F085series of high-speed, low-side automotive qualified gate drivers from Fairchild Semiconductor offer flexibility for power supply and other high-efficiency MOSFET switching applications, providing a wide selection of feature and performance combinations to create compact, highly efficient and reliable designs.

These AEC-Q100 qualified drivers are available in an SO8 package with a choice of TTL or CMOS input thresholds. This ensures the best possible design compatibility. The drivers have two inputs for each channel (either Dual-input (+ and – logic), Inverting and Enable, or Non-inverting and Enable) offering design flexibility.

Key Features:

  • Qualified to AEC-Q100 requirements (shown by flow code "_F085"),
  • Compound MillerDrive architecture for strong gate drive,
  • Short and well-controlled time delays (<20ns propagation delays for >1MHz switching) allows paralleling drivers, and optimizing drive timing to maximize efficiency,
  • Fail-safe inputs: output held low if no input signal is present,
  • 20V Abs max >4kV ESD and >500mA reverse current,
  • -40 to +125 degrees C ambient operating temperature range.
