Component

dual gate driver2 A peaklow-side driverSOIC-8MOSFET driverIGBT driver

DOS4427 is a dual 2 A peak, non-inverting low-side MOSFET and IGBT gate driver in SOIC-8, intended for 4.5 V to 20 V supplies.

Best for

  • Two independent low-side MOSFET gate-drive channels
  • Switch-mode power supplies and DC-DC converters
  • Motor-drive and pulse-drive circuits

Avoid if

  • A high-side or isolated gate driver is required
  • Supply voltage exceeds 20 V during normal operation
  • Verified lifecycle or qualification information is mandatory

Check before use

  • Gate charge and required switching speed
  • VCC bypass layout and ground return path
  • Actual output current and thermal dissipation at switching frequency
