The new Infineon EiceDRIVER 1EDB family of single-channel gate-driver IC provides galvanic input-to-output isolation of 3 kV rms (UL 1577) that ensures rugged ground-loop separation.
Their common-mode transient immunity (CMTI) exceeds 300 V/ns, making these devices interesting for hard switching applications enabling numerous topologies.
The new 1EDB family includes four parts (1EDB6275F, 1EDB7275F, 1EDB8275F and 1EDB9275F) and is optimized for both high/low-side applications.
They can solve PCB-layout problems, common in high-power applications such as server and telecom switched-mode power supplies (SMPS) as well as uninterruptable power supply (UPS) systems.
All products come with separate and very low ohmic (0.95 Ω) source and (0.48 Ω) sink outputs for ease of design, offering typical drive strengths of 5.4 A peak source and 9.8 A peak sink.
This feature plays a vital role in reducing the switching losses of power MOSFETs. The input-to-output propagation delay accuracy is +/- 4 ns helping to cut switching losses, which is essential in fast-switching applications. The typical output stage clamping speed is as short as 20 ns and supports functionally safe system operation, especially during start-up.
Designers can choose between four different output under-voltage lockout (UVLO) options
