Cosine Nanoelectronics Launches 600V Half-Bridge Driver COS2103 for Inverter Topologies

The COS2103 is designed to operate with a floating bus voltage up to 600V, making it ideal for variable speed BLDC motor drives, high-frequency induction heating, and solar micro-inverters. It features matched propagation delay times and a built-in 500ns deadtime circuit that prevents shoot-through current in half-bridge configurations.

Key Operational Parameters

Laboratory audits indicate that the floating high-side channel operates with high noise immunity under dV/dt transients up to 50V/ns, ensuring robust performance in electrically noisy environments.

• Floating Voltage: +600V offset voltage capability.
• Output Drive: 290mA source / 600mA sink gate drive current.
• Deadtime: Built-in 500ns to prevent phase leg short circuits.
