CA-IS3211SCWG

The CA-IS3211 devices are a family of single-channel, optocompatible reinforced isolated gate driver capable of sinking 6A and sourcing 5A currents. These devices operate with dual supplies or a single supply of 14V to 30V wide voltage range of VCC - VEE, making them ideal to drive power MOSFET, IGBT or silicon-carbide (SiC) transistors in various inverter, motor control or isolated power supply systems. The CA-IS3211 can be configured as low-side and high-side drivers. The CA-IS3211Sx offers dual separate output terminals: OUTH and OUTL. The driver output is pulled to low state to turn-off external power transistors when VCC supply input is either not powered, open-circuit or in UVLO. All devices have integrated digital galvanic isolation using Chipanalog’s proprietary capacitive isolation technology and feature isolation with a withstand voltage rating of up to 7.5kVRMS for 60 seconds and minimum common-mode transient immunity (CMTI) of 100kV/μs. These devices can be used as drop-in replacement for the industry standard optocoupler-based gate drivers while providing high CMTI, low propagation delay, small pulse width distortion and small part-to-part skew. The input stage is an analog diode which means long term reliability and excellent aging characteristics.

The CA-IS3211 devices are available 8-pin super wide-body SOIC packages, all devices are rated for operation at junction temperatures of -40°C to +150°C.
