LTC4444 - High Voltage Synchronous N-Channel MOSFET Driver

The LTC4444 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. The powerful driver capability reduces switching losses in MOSFETs with high Gate capacitance. The LTC4444s pull-up for the top Gate driver has a peak output current of 2.5A and its pull-down has an output impedance of 1.2. The pull-up for the bottom Gate driver has a peak output current of 3A and the pull-down has an output impedance of 0.55. The LTC4444 is congured 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 contains undervoltage lockout circuits that disable the external MOSFETs when activated. The LTC4444 also contains adaptive shoot-through protection to prevent both MOSFETs from conducting simultaneously. The LTC4444 is available in the thermally enhanced 8-lead MSOP package.
