About Intersil SR FET Drivers

Intersil's family of high-speed, 6A, dual channel MOSFET drivers are available with and without enable inputs for each channel. These SR FET drivers can be customized to fit the needs of your project with a variety of input logic thresholds including 3.3V (CMOS), 5.0V (CMOS or TTL compatible) and CMOS thresholds that are proportional to VDD.

Precision thresholds on all logic inputs allow the use of external RC circuits to generate accurate and stable time delays on both inputs, INA and INB. This capability is very useful for dead time control. Alternatively, the ISL89166/7/8 drivers feature programmable delays for improved accuracy.

At high switching frequencies, these MOSFET drivers use very little bias current. Separate, non-overlapping drive circuits are used to drive each CMOS output FET to prevent shoot-through currents in the output stage.

Family Values

  • Typical ON-resistance <1Ω
  • Specified Miller Plateau Drive Currents
  • Very Low Thermal Impedance (θJC = 3°C/W)
  • Hysteretic Input Logic Levels
  • Precision Threshold Inputs for Time Delays with External RC Components
  • 20ns Rise and Fall Time Driving a 10nF Load.

Applications

  • Synchronous Rectifier (SR) Driver
  • Switch Mode Power Supplies
  • Motor Drives, Class D Amplifiers, UPS, Inverters
  • Pulse Transformer Driver
  • Clock/Line Driver
