UCC20520DW

The UCC20520DW from Texas Instruments is a reinforced isolated dual-channel gate driver designed for high-voltage applications. It provides a withstand isolation voltage of 5700 Vrms and a working isolation voltage of 2121 Vrms, making it suitable for driving IGBT, MOSFET, and SiCFET power switches.

This gate driver features peak output currents of 4A sourcing and 6A sinking, with a wide output supply voltage range of 9.2V to 25V and an input supply voltage range of 3V to 18V. It operates within an extended temperature range of -40°C to 125°C. Key electrical specifications include a typical propagation delay of 19 ns, a minimum pulse width of 10 ns, and a maximum pulse-width distortion of 6 ns. The device also boasts a high common-mode transient immunity (CMTI) greater than 100 V/ns.

Packaged in a 16-SOIC (0.295", 7.50mm Width) surface-mount package, the UCC20520DW is designed for efficient power management solutions. Its features include disable functionality and programmable dead-time control, enhancing design flexibility and system reliability. The driver supports CMOS and TTL input thresholds and includes undervoltage lockout protection.

This component is ideal for applications requiring robust isolation and precise gate drive control, such as in power supplies, motor drives, and industrial automation systems where high voltage transients and noise are prevalent.
