Chipanalog CA-IS3211SBG Isolated Gate Driver

Chipanalog CA-IS3211SBG

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
