Featuring extra channel for PFC switch or inverter brake, 3-phase Model IRS26302D is suited for medium power appliance motor control applications. Device integrates power MOSFET/IGBT gate drivers with 3 high-side and 3 low-side referenced output channels to provide 200/350 mA drive current at up to 20 V MOS gate drive capability, operating up to 600 V. Negative Vs immunity circuitry is incorporated to protect system from catastrophic events.
IR Introduces Protected Three-Phase 600V IC Featuring Extra Channel for PFC or Brake and Ground Fault Protection
Featuring Extra Channel for PFC or Brake and Ground Fault Protection
EL SEGUNDO, Calif. - International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today introduced the IRS26302D protected 600V three-phase gate driver IC with ground fault protection. The IC has a seventh gate drive channel for a power factor correction (PFC) switch or inverter brake, making it well-suited to medium power appliance motor control and many other general-purpose three-phase inverter applications.
"With its integrated bootstrap functionality, PFC or brake, and ground fault protection, our latest high-voltage IC is ideal for three-phase inverter applications with space limitations. As part of our latest HVIC generation, this compact IC also delivers many protection features including our negative Vs immunity circuitry, to withstand very large negative Vs transients seen during high-current switching and short-circuit conditions," said Aengus Murray, IR director of motor control marketing.
The IRS26302D integrates power MOSFET/IGBT gate drivers with three high-side and three low-side referenced output channels to provide 200mA/350mA drive current at up to 20V MOS gate drive capability operating up to 600V. An additional low-side driver is provided for a PFC switch or inverter brake.
The IC incorporates negative Vs immunity circuitry to protect the system from catastrophic events that can be seen during high-current switching and short-circuit conditions in addition to ground fault protection, critical features 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 from space constraints and to simplify design, the IRS26302D features 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.
Part of IR's G5 HVIC platform, the new IC utilizes 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, the IRS26302D features under-voltage lock-out protection, integrated deadtime protection, shoot-through protection, a shutdown input, fault-reporting, and is compatible with 3.3V input logic.
Availability and Pricing
Available in 44-pin PLCC, the IRS26302D is US $2.44 each in quantities of 100,000 units. Production orders are available immediately. The devices are RoHS compliant and prices are subject to change.
