The CA-IS3211 devices are a family of single-channel, optocompatible isolated gate driver capable of sinking 6A andsourcing 5A currents. These devices operate with dualsupplies or a single supply of 10V to 30V (8V UVLO version)or 14V to 30V (12V UVLO) wide voltage range of VCC - VEE,making them ideal to drive power MOSFET, IGBT or siliconcarbide(SiC) transistors in various inverter, motor control orisolated power supply systems. The CA-IS3211 can beconfigured as low-side and high-side drivers. The CAIS3211V_ offers single terminal gate drive output: VOUT andthe CA-IS3211S_ offers dual separate output terminals:OUTH and OUTL. The driver output is pulled to low state toturn-off external power transistors when V_CC supply input iseither not powered, is open-circuit or is in UVLO.

All devices have integrated digital galvanic isolation usingChipanalog’s proprietary capacitive isolation technologyand feature isolation for a withstand voltage rating of up to5.7kV_RMS for 60 seconds with minimum common-modetransient immunity (CMTI) of 150kV/μs. These devices canbe used as drop-in replacement for the industry standardoptocoupler-based gate drivers while providing high CMTI,low propagation delay, small pulse width distortion andsmall part-to-part skew. The input stage is an analog diodewhich means long term reliability and excellent agingcharacteristics.

The CA-IS3211 devices are available either in a 6-pin or 8-pin wide-body SOIC packages, and 8-pin DUB package. Alldevices are rated for operation at junction temperatures of-40°C to +150°C.
