Description

CA-IS3211 Isolated Gate Driver Overview

The CA-IS3211 is an optocoupler-compatible single-channel isolated gate driver, designed for driving MOSFET, IGBT and SiC devices. The isolation level reaches 5.7kVRMS, and the chip can provide 5A sourcing and 6A injecting peak current capabilities.

The CA-IS3211’s supply voltage range up to 30V allows for the use of bipolar supplies, efficiently driving IGBTs and SiC power FETs. The chip’s performance highlights include high common-mode transient immunity (CMTI), low propagation delay, and low pulse width distortion. Strict process control ensures the chip’s consistency.

The input stage features an analog diode, which offers better long-term reliability and aging characteristics than conventional optocoupler-isolated gate driver LEDs. The high performance and reliability of the chip make it suitable for various applications, including industrial power supplies, photovoltaic inverters, vehicle chargers, DC motor control, and automotive air conditioning and heating systems.

The CA-IS3211 is capable of driving power tubes on both the high-voltage and low-voltage sides. It is fully compatible with traditional optocoupler gate drivers and significantly enhances driving performance.
