The AUIRS2301S is a rugged, general purpose driver IC with independent high- and low-side referenced output channels, offering a gate drive supply range from 5V to 20V. The device’s output drivers feature a high-pulse current buffer stage designed for minimum driver cross-conduction while the floating channel can be used to drive N-channel power MOSFETs or IGBTs in the high-side configuration operating up to 600V. Additionally, the IC features negative voltage spike (-Vs) immunity to protect the system against catastrophic events during high-current switching and short circuit conditions.
The new device, which is 3.3V, 5V and 15V logic compatible with standard CMOS or LSTTL output, also features output current capability of 120mA/250mA, under-voltage lockout and matched propagation delays for both channels, outputs in phase with inputs, and lower di/dt gate driver for better noise immunity.
The AUIRS2301S 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.
The IC is qualified according to AEC-Q100 standards, features an environmentally friendly, lead-free and RoHS compliant bill of materials, and is part of IR’s automotive quality initiative targeting zero defects.
