Diodes DGD05473 their advanced high-frequency gate drivers, designed for driving N-channel MOSFETs in a wide temperature range from -40°C to +125°C. These gate drivers offer several features to enhance performance, protection, and ease of use.
The flagship product, the DGD05473 high-frequency gate driver, provides a floating high-side driver capable of handling voltages up to 50 V. Its logic inputs are compatible with both standard TTL and CMOS levels, making it easy to interface with microcontrollers (MCUs). The compatibility extends to as low as 3.3 V, ensuring seamless integration with various digital systems.
To safeguard MOSFETs against supply loss, the DGD05473 incorporates undervoltage lockout (UVLO) protection for both the high-side and low-side drivers. This feature ensures that the MOSFET remains protected even during voltage fluctuations or power disruptions. Additionally, cross conduction prevention logic is implemented to prevent simultaneous activation of the HO and LO outputs, adding an extra layer of protection for MOSFETs.
The gate driver's fast and well-matched propagation delays enable higher switching frequencies, allowing for a more compact power switching design. This feature facilitates the use of smaller associated components, resulting in space savings and improved efficiency. Furthermore, the DGD05473 includes an internal bootstrap diode, minimizing the need for additional external components and reducing the overall footprint.
Packaged in a U-DFN3030-10 package, the DGD05473 gate driver guarantees reliable operation over a wide temperature range, from -40°C to +125°C. This extended temperature capability makes it suitable for demanding applications that require reliable performance in harsh environments.
In summary, Diodes' high-frequency gate drivers offer versatile functionality and protection features for driving N-channel MOSFETs. With their extended temperature range, wide logic level compatibility, MOSFET protection mechanisms, and compact design, these gate drivers provide an efficient and reliable solution for various industrial and automotive applications.
