Modern washers, fans, air conditioners and pump manufacturers require state-of-the-art electronic components to deliver more and more features to the end user. The aim is to create an energy-efficient appliance, in less time – without increasing the overall system cost.

The IRS2330/IRS2332(D) from International Rectifier is a high-voltage, high speed power MOSFET and IGBT driver with three independent high- and low-side referenced output channels for three-phase applications. The bootstrap diode functionality has been integrated into this device to reduce the component count and PCB size. A current trip function which terminates all six outputs can be derived from an external current sense resistor. A ground-referenced operational amplifier is available to provide analog feedback of the bridge current via an external current sense resistor.
