The LTC4444IMS8E#PBF 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 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. It contains under-voltage lockout circuits that disable the external MOSFETs when activated. Adaptive shoot-through protection prevents both MOSFETs from conducting simultaneously.
