International Rectifier, IR® (NYSE:IRF), a world leader in power management technology, introduced the IRS2336xD protected 600V three-phase gate driver ICs with integrated bootstrap functionality for appliance motor control, servo drives, micro-inverter drives, and a wide range of general purpose applications.
“Our latest high-voltage gate drivers are ideal for three-phase applications that require industrial level ruggedness. These new ICs feature IR’s proprietary 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. Additionally, an advanced input filter improves system performance while the integrated bootstrap functionality reduces the circuit footprint,” said IR’s HVIC product manager David New.
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.
Part of International Rectifier’s G5 HVIC platform, these devices incorporate advanced functionality including negative Vs immunity circuitry to protect the system from catastrophic events that can be seen during high-current switching and short-circuit conditions, critical for industrial systems that require high levels of robustness and reliability. Also, 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 utilize IR’s advanced high-voltage IC process which incorporates next-generation 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.
Availability and Pricing
Available in 28-pin SOIC and 44-pin PLCC, pricing for the IRS2336xD ICs begin at US $1.89 each in quantities of 100,000 units. Production orders are available immediately. The devices are RoHS compliant and prices are subject to change.
