  RE: I need to control 4 N Channel MOSFET H - Bridge with Supply voltage ( of the bridge) of up to 100V and the Logic command voltage is 1.8V.

  Hi, Shimon, Thanks for your interest in our products. Unfortunately, we don’t have a gate driver with logic thresholds compatible with a 1.8V inputs, so you will to use a level shifter. Look at UCC27282. I think coupled with a level shifter, it will...

  RE: UCC27211: High frequency output problem

  Hello Jung Kyoung su. 10MHz is fairly high operating frequency which will result in narrow pulse widths. The input pulse response of the driver is the main consideration regarding high frequency operation. You mention 50ns dead time but the period...

  RE: UCC27211: does UCC27211DPRR have interlock function?

  Hello Max, Thank you for supporting the UCC27211. The UCC27211 does not have the interlock to prevent LO and HO outputs from being on at the same time. There are some topologies, 2 switch forward, secondary SR, where you need the LO and HO on at the...

  [FAQ] UCC27282: Gate driver IC prevents damage from negative voltage spikes due to stray layout inductance and protects against cross conduction with built-in interlock in 100V half-bridge applications

  Part Number: UCC27282 Advanced power supply designers often face challenges when designing robust, high density, and high efficiency power supplies. To achieve these, they often ask for gate driver ICs that are as small as possible, but at the same...

  RE: 100V half bridge not isolated gate driver?

  Hello Antonio, For the 100V drivers that are similar to the L6388, what I found is that the L6388 is obsolete and the L6388E datasheet is available. So my comments are on the L6388E. For a driver that has the closest drive current capability, the...

  RE: UCC27282: Minimum Input turn-on and turn-off time

  Thanks Ritesh, I accidentally missed that parameter in the datasheet. This is for a buck converter operating at 600Khz. That answers the question! Thanks, Kyle
