The LTC4444-5 is a high frequency high voltage gate driver that drives two N-channel MOSFETs in a synchronous DC/DC converter with supply voltages up to 100V. This powerful driver reduces switching losses in MOSFETs with high gate capacitance.

The LTC4444-5 is configured for two supply-independent inputs. The high side input logic signal is internally level-shifted to the bootstrapped supply, which may function at up to 114V above ground.

The LTC4444-5 contains undervoltage lockout circuits that disable the external MOSFETs when activated. Adaptive shoot-through protection prevents both MOSFETs from conducting simultaneously.

Applications

  • Distributed Power Architectures
  • Automotive Power Supplies
  • High Density Power Modules
  • Telecommunication Systems
