Automotive, Single-channel Reinforced Isolated Gate Driver

The CA-IS3215/6 devices are a family of single-channel reinforced isolated gate driver capable of sinking 15A and sourcing 15A peak-current. These devices operate with dual supplies or a single supply of up to 33V wide voltage range of VDD - VEE, making them ideal to drive high-power MOSFET, IGBT or silicon-carbide(SiC) transistors in various inverter, motor control or isolated power supply systems.

The CA-IS3215/6 gate drivers integrate extensive active protection, such as active Miller clamp, UVLO detection on both control-side and driver-side supply, over-current and short-circuit fault alarm and protection, to optimize SiC and IGBT control and improve system reliability. All devices have integrated digital galvanic isolation between control-side and driver-side using Chipanalog’s proprietary SiO2 capacitive isolation technology which features isolation for a withstand voltage rating of up to 5.7kVRMS for 60 seconds with minimum common-mode transient immunity (CMTI) of 150V/ns, support up to 1500VRMS isolation working voltage and 12.8kVPK surge rating.

The CA-IS3215/6 devices are available in a 16-pin widebody SOIC package with creepage and clearance > 8mm. All devices are rated for operation at junction temperatures of -40°C to +150°C. Higher operation temperature range extends gate driver designs in the industrial and automotive applications.
