600V automotive qualified MOSFET and IGBT driver ICs from IR for gate drive applications

International Rectifier has released a family of rugged 600V Automotive qualified MOSFET and IGBT driver ICs for energy-efficient automotive gate drive applications including Piezo and common rail injection, starter alternator, electronic power steering, fan and compressor applications.

The family has five high speed power MOSFET and IGBT driver ICs. These driver ICs provides output source/sink current capability up to +1.9A/-2.3A for rapid turn-on and turn-off time, while high current capability enables the new devices to efficiently drive larger switches for higher power applications.

This family includes:

--Two half-bridge drivers:
The AUIRS2184S, featuring a fixed deadtime of 500ns.
The AUIRS21844S featuring programmable deadtime between 400ns and 5µs.

--Three dual channel high-side and low-side driver ICs:
The AUIRS2181S, AUIRS21811S and AUIRS21814S, dual channel high-side and low-side driver ICs with various input logic and propagation delays.

"This new family of 600 V Q100 qualified ICs expands IR's dedicated automotive offering to provide the flexibility to design an optimized gate drive for a given system," said Marzak Li, product marketing manager, IR's Automotive Products Business Unit.

These drivers ICs feature high-voltage integrated circuit (HVIC) and latch immune CMOS technologies to offer ruggedized monolithic construction. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high-side configuration. In addition, the devices feature benchmark negative voltage spike immunity for reliable operation even under extreme switching conditions and short circuit events.

Other key features common to the family include under-voltage lockout for both channels, 3.3V and 5V input logic compatibility and lower di/dt for noise immunity. A separate Vss logic ground pin featured in specific parts offers higher immunity to transient shifts on COM voltage.

The devices are qualified according to AEC-Q100 standards, feature an environmentally friendly, lead-free and RoHS compliant bill of materials.
