International Rectifier (IR) has introduced the IR2301 and IR2302 high voltage gate driver ICs that are targeted for automotive motion control applications, such as variable speed motor drives, common-rail injectors, and valve control systems.

The products offer extended supply voltage range that allows safe operation from 600V to 5V. The under-voltage lockout circuit switches off both outputs as soon as the supply voltage falls below 4.7V, and the outputs are released when the supply voltage exceeds 5V. The ICs are 3.3-, 5-, and 15V input logic-compatible.

The IR2301 offers a high-side and low-side driver output controlled via two separate CMOS/LSTTL-compatible inputs. The low propagation delays for turn-on and turn-off, combined with accurate propagation delay matching of both channels simplify circuits and support high frequency switching up to 100kHz.

The IR2302 features an integrated cross-conduction prevention logic that automatically prevents MOSFET or IGBT shoot-through situations in the H-bridge legs when changing motor direction. The half-bridge driver configuration of the IR2302 is controlled via a standard CMOS/LSTTL compatible input. An additional control input is used to shut down the IC.

The ICs are available for $1.00 each for the IR2301 and the IR2302 (8-pin DIP), and $1.02 each for the IR2301S and IR2302S (SO-8) in 10,000-unit quantities.
