Gate driver ICs provide rugged solution

An International Rectifier product story

Edited by the Electronicstalk editorial team Oct 26, 2007

International Rectifier IRS2336xD gate driver ICs are suitable for three-phase applications that require industrial level ruggedness.

International Rectifier has introduced the IRS2336xD protected 600V three-phase gate driver ICs with integrated bootstrap functionality for appliance motor control, servo drives, micro-inverter drives and general purpose applications.

IR's latest high-voltage gate drivers are suitable for three-phase applications that require industrial level ruggedness.

These new ICs feature IR's negative Vs immunity circuitry, allowing the devices to withstand the very large negative Vs transients that are seen during high-current switching and short-circuit conditions.

An input filter improves system performance while the integrated bootstrap functionality reduces the circuit footprint.

Integrating power MOSFET/IGBT gate drivers with three high-side and three low-side referenced output channels, the IRS2336xD ICs provide 180mA/330mA drive current at up to 20V MOS gate drive capability operating up to 600V.

An advanced input filter has been integrated to reject noise and reduce distortion, improving system performance in many motor control applications.

To address the needs of applications suffering for space constraints and to simplify design, the IRS2336xD ICs feature integrated bootstrap functionality.

This functionality can reduce the bootstrap power supply from six components to three, while providing VBS over-voltage protection for the system through the use of additional integrated intelligent protection circuitry.

The new devices use IR's high-voltage IC process which incorporates high-voltage level shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability.

In addition to the over-current and over-temperature detection input, these ICs feature under-voltage lock-out protection, integrated deadtime protection, shoot-through protection, a shutdown input, fault-reporting and are compatible with 3.3V input logic.
