ChipAnalogue has unveiled the CA-IS3214, a new single-channel reinforced isolated gate driver designed to set a new benchmark for driving advanced power semiconductors like SiC MOSFETs and IGBTs. Built on robust SiO₂ capacitive isolation technology, this driver delivers exceptional performance and reliability, making it an ideal solution for demanding applications in motor drives, new energy systems, and industrial power supplies.
The driver's core specifications are engineered for robustness and precision. It features a powerful 10A peak source/sink current capability, enabling it to drive power switches rated up to 2121V. Its superior isolation performance supports a continuous 1.5kVRMS working voltage, with a surge immunity of 12.8kVPK and a guaranteed isolation barrier lifespan of over 40 years. Its exceptional Common-Mode Transient Immunity (CMTI) of >150kV/μs ensures stable operation in electrically noisy environments.
Engineered for speed and flexibility, the CA-IS3214 boasts a swift 80ns typical propagation delay with minimal pulse-width distortion and channel matching. It operates from a wide input supply range of 3.0V to 5.5V and provides an output drive supply up to 33V. The driver offers design flexibility with two Under-Voltage Lockout (UVLO) options and features 40ns input filter immunity optimized for the switching characteristics of SiC and IGBTs.
Multiple variants cater to diverse needs: the CA-IS3214MxG includes an integrated 5A active Miller clamp, while the CA-IS3214SxG and CA-IS3214TSCG offer separated output pins. Housed in a SOIC8-WB package with over 8mm creepage and clearance, it delivers 5700VRMS isolation and operates reliably across an extended -40°C to 150°C junction temperature range, ensuring durability in harsh conditions.
The driver is well-suited for a broad spectrum of power conversion applications, including motor inverters, EV onboard chargers (OBC), solar inverters, energy storage systems, charging桩 modules, servo drives, and industrial UPS units. It represents a key addition to ChipAnalogue's comprehensive portfolio of isolated gate drivers, further strengthening China's domestic supply chain for critical power electronics components.
