PRESS RELEASE Rugged, Reliable 600V IC for General Purpose Automotive Drive Applications DATA SHEET The AUIRS2301S is a rugged, general purpose driver IC with independent high- and low-side referenced output channels, offering a gate driver supply range from 5V to 20V. The AUIRS2301S expands IR’s portfolio of 600V ICs designed specifically to address the needs of demanding general purpose drives used in harsh automotive environments such as under-the-hood applications that required a rugged, reliable and flexible solution. HI-RES GRAPHIC Automotive HOME PAGE Features Floating channel designed for bootstrap operation Fully operational to +600V Output current capability of 120mA/250mA Tolerant to negative transient voltage – dV/dt immune Gate drive supply range from 5V to 20V Undervoltage lockout for both channels 3.3V, 5V and 15V input logic compatible Matched propagation delay for both channels Outputs in phase and inputs Lower di/dt gate driver for better noise immunity Leadfree, RoHS compliant Automotive qualified per AEC-Q100 Advantages The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction while the floating channel can be used to drive an N-channel power MOSFET or IGBT in the high-side configuration which operates up to 600V. The logic input is compatible with standard CMOS or LSTTL output down to 3.3V logic. The IC features negative voltage spike (Vs) immunity to protect the system against catastrophic events during high-current switching and short circuit conditions. January 2010
