The IRMD2214SS demo board is an evaluation board for IR2214SS gate driver. With three connected IR2214SS (see the device datasheet), IRMD2214SS is designed to drive 3-phase power modules with pinout compatible to ECONO2-6PACK. The board can drive AC or Brushless motors using power modules with up to 50A output current. The board is a flexible solution for different applications and can be customized providing place for external components. The control signals are 3.3V CMOS compatible; three-phase shunt resistor (with sensing pins) can be placed for current loop control; power module short circuits are managed synchronizing the IGBT turn off in a local network. Board layout reduces the noise coupling between high and low voltage signals and EM emissions.
