International Rectifier  (IR) has introduced IRS233x(D) family of three-phase gate driver ICs for low-, mid-, and high-voltage motor drive applications including permanent magnet (PM) motor drives for air conditioners, washing machines, pumps and fans, and micro, mini and general purpose inverter drives.

The IRS233x(D) is a high-voltage, high speed power MOSFET and IGBT three-phase bridge- driver with referenced output channels to provide 200 mA/420 mA drive current at up to 20 V MOS gate drive capability operating up to 600 V.

The IRS233x(D) family of three-phase gate driver ICs feature an integrated ground-referenced operational amplifier to provide analogue feedback of the bridge current via an external current sense resistor and optional integrated bootstrap diode to reduce external part count and reduce PCB size.

“With its high level of integration, including an operational amplifier and bootstrap diode, the IRS233x(D) family simplifies and shrinks motor drive design while providing a high level of reliability and ruggedness,” said Henning Hauenstein, IR’s vice president Product Marketing, Automotive, Appliance and Industrial Motion.

The IRS233x(D) family of three-phase gate driver ICs provides comprehensive protection including proprietary negative voltage spike (Vs) immunity for safe operation under extreme switching conditions and short circuit events. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction.

Propagation delays are matched to simplify use at high frequencies. The floating channel can be used to drive N-channel power MOSFET or IGBT in the high-side configuration.

The IRS233x(D) family of three-phase gate driver ICs utilise IR’s advanced high-voltage IC process which incorporates new generation high-voltage level-shifting and termination technology to deliver good electrical over-stress protection and higher field reliability.

In addition to over-current detection input, the IRS233x(D) features under-voltage lock-out protection, integrated deadtime protection, shoot-through protection, fault-reporting, and is compatible with 3.3 V input logic.
