2EDB8259Y

Overview

Fast, robust, dual-channel, functional isolated MOSFET gate drivers with accurate and stable timing.

The EiceDRIVER™ 2EDB8259Y is a dual-channel isolated gate driver IC with floating outputs. The strong 5 A/9 A source/sink dual-channel gate driver comes with a very high 150 V/ns CMTI (common mode transient immunity) for robust operation with CoolMOS™, CoolGaN™ GIT HEMTs in high-power switching noise environment.

The very short propagation delay of 38ns is provided with low variation over temperature and production which enables the power system design to achieve higher efficiency through very tight timing control across the safety isolation barrier. Safety certificates in accordance with UL1577 and GB4943.1 are available. 2EDB8259Y is available in a narrow-body 150 mil DSO-14 package.

Summary of Features

  • up to 8000 Vpk VIOTM robust input-to-output isolation meeting the latest components standards (IEC60747-17)
  • Available system standards certificates (EN 62368-1, GB4943.1)  
  • Channel-to-channel isolation
  • Accurate timings
  • High CMTI (common mode rejection) > 150 V/ns
  • < 2 µs fast UVLO start-up time
  • Fast active clamping of the output for supply below UVLO
  • Optional Dead-time control and shoot-through protection (DTC/STP)
  • 14-pin package with increased channel-to-channel creepage

Benefits

  • System safe isolation
  • Simplified system safety approval
  • Flexible driving (driving of two floating switches at different source potentials, driving of 4-pin kelvin source MOSFETs) or simply robustness against ground bounce in noisy environments
  • Perfect signal synchronization for increased system efficiency
  • Reliable system operation at high switching frequencies and driving of WBG (wide bandgap) devices
  • Symmetrical operation in bootstrapped system with benefit on system reliability (reduced risk of saturation of the main transformer or hard commutation in LLC)
  • Enabling safe operation in bootstrapped system during start-up
  • Protection against input overlap in case of noisy conditions as output short circuits
  • Operation at higher bus voltages or in worst pollution degree environments
