MOSFETs improve 12V-input converter efficiency
Two new 20V HEXFET power MOSFET families from International Rectifier are designed to increase efficiency by up to 4% in 12V-input DC/DC convertors.
With its integrated bootstrap functionality, PFC or brake and ground fault protection this latest high-voltage IC is suitable for three-phase inverter applications with space limitations.
As part of IR's latest HVIC generation, this compact IC also delivers many protection features including negative voltage immunity circuitry, to withstand very large negative voltage transients seen during high-current switching and short-circuit conditions.
The IRS26302D integrates power Mosfet/IGBT gate drivers with three high-side and three low-side referenced output channels to provide 200/350mA drive current at up to 20V MOS gate drive capability operating up to 600V.

Rad-hard MOSFETs protect and survive
With high radiation hardness and unparalleled single event effect (SEE) immunity, International Rectifier's new R5 MOSFETs are well suited for systems that must survive penetrating gamma rays.
An additional low-side driver is provided for a PFC switch or inverter brake.
The IC incorporates negative voltage 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.
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 IC uses the company'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.
