The UCC21521CDWR is an integrated circuit for isolators and gate drivers designed specifically for solar energy applications. This product combines a complete isolated gate drive circuit with protection for the optical switch, thereby eliminating the need for a separate voltage source or circuit for the LED switch. This product is designed to be used with a single line, and is capable of up to a 400 A peak rating for controlling voltage levels from 8 V to 13 V in DC systems. Its application fields are photovoltaic systems, isolated switch controllers, motor control, and inverters.

Working Principle

The UCC21521CDWR works by providing an isolation voltage of up to 690V DC for controlling the voltage level of the switch. In photovoltaic applications, it provides an effective, low-loss regulation of solar cell output voltage. This is done by providing a logic level input signal, which in turn controls the amount of current passed through the diode, thereby controlling the output voltage. The device also has two onboard LED drivers for displaying status. The LED drivers are protected by an overvoltage protection circuit that limits the reverse voltage across the device.

Additionally, the UCC21521CDWR features a low power and low noise operation of up to -40dB, making it ideal for high efficiency photovoltaic applications. Furthermore, the device is equipped with a PEMF optimized software, enabling the device to interact better with the system in terms of power consumption and data transmission. This allows the device to run in low power mode when power is not needed. Additionally, it comes with an ESD protection circuit which reduces the sensitivity to external electrostatic shocks and field interference.

Conclusion

In conclusion, the UCC21521CDWR is an integrated circuit for isolators and gate drivers designed specifically for solar energy applications. It is designed to provide an effective, low-loss regulation of solar cell output voltage while also providing an isolation voltage of up to 690V DC. Furthermore, this product features low power and low noise operation, a PEMF optimized software, and an ESD protection circuit. As such, it is an ideal choice for photovoltaic applications, isolated switch controllers, motor control, and inverters.
