Infineon Launches A New Generation Of Dual-Channel Isolated Gate Driver ICs

htelec.net takes you to know that Infineon has launched a new generation of dual-channel isolated gate driver IC.

Today, a 3.3 kW switched-mode power supply (SMPS) is achieved by employing superjunction (SJ silicon) power MOSFETs and silicon carbide (SiC) power MOSFETs in the totem-pole PFC stage, as well as gallium nitride (GaN) capable of meeting high-voltage DC-DC power conversion requirements. The latest technologies such as GaN) power switches enable the power density to reach 100 W/inch3. Digital control of PFC and DC-DC is as important as an excellent gate drive solution to improve energy efficiency and enhance robustness. In order to meet In response to the latest design and application requirements, Infineon Technologies AG has launched a new generation of dual-channel electrically isolated EiceDRIVER™ gate driver IC product family.

With multiple undervoltage lockout (UVLO) threshold options, isolation levels, and different packaging technologies, the product family can provide a complete solution for a variety of applications. The new product portfolio combines robust isolation technologies that meet the latest industry standards with The combination of excellent electrical parameters enables efficient\reliable operation in a wide operating temperature range and prolongs the service life of the device. This series of drivers is widely used and is suitable for server and telecom SMPS\solar inverters and energy storage systems \Motor drive and battery-powered applications\EV charging and high-performance computing and other various applications.

Compared with the previous generation, the new generation of EiceDRIVER introduces the DSO 14-pin package, which can increase the creepage distance between channels; at the same time, the built-in dead time control and breakdown protection function can also shorten the UVLO start-up time. The new generation EiceDRIVER adopts powerful isolation technology that complies with the industry's latest device-level isolation standards (VDE 0884-11\IEC 60747-17). In addition, this series of drivers also adopts a highly compact LGA 4x4 mm2 package, which can save up to 36% space. One of the important improvements and upgrades made by developers to the new generation of EiceDRIVER is that the electrical isolation technology is integrated in the gate driver IC, which has passed the IEC 60747-17 certification. Obtained IEC 60747-17 Certification means that these products have a service life of up to 20 years and meet the highest safety standards.

Shorter UVLO start-up time (reduced from 5μs to 2μs) speeds up the start-up of SMPS and avoids the saturation of the main power transformer. In addition, the new generation IC has a special output clamping circuit, which realizes effective Source output clamping function to quickly reject output noise even when the channel is "not active". This versatile method prevents the bootstrap start-up process while the gate driver supply is still below the UVLO turn-on threshold A dangerous half-bridge through event occurred.

The new generation of gate driver ICs has configurable shoot-through protection (STP) and dead-time control (DTC) built into the hardware. These two functions can be used as a second level safety mechanism to provide further protection to ensure that the gate driver The IC can operate safely\reliably. In addition, the innovative package design removes unused or previously called "no-connect" pins, which improves the isolation level between channels and the flexibility of PCB layout, thereby reducing design time. the difficulty of developing the circuit.
