INTRODUCTION
The IRMD22141SS demo board is an evaluation board for IR22141SS gate driver. With three connected
IR22141SS (see the device datasheet), IRMD22141SS is designed to drive 3-phase power modules with
pin-out 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.
