CA-IS3211CVBJ

The CA-IS3211C devices are a family of single-channel, opto- compatible isolated gate driver capable of sourcing 4.7A and sinking 6A currents. These devices operate with dual supplies or a single supply of 10V to 30V (8V UVLO version) or 14V to 30V (12V UVLO version) 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-IS3211C can be configured as low-side and high-side drivers. The CA IS3211CVx offers single terminal gate drive output: VOUT and the CA-IS3211CSx 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. 

 The CA-IS3211C devices have integrated digital galvanic isolation using Chipanalog’s proprietary capacitive isolation technology and feature isolation with a withstand voltage rating of up to 5.7kVRMS/3.75kVRMS for 60 seconds and minimum common-mode transient immunity (CMTI) of 150kV/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-IS3211C devices are available either in a 6-pin or 8 pin wide-body SOIC packages, and 8-pin DUB package. All devices are rated for operation at junction temperatures of -40°C to +150°C.
