Description

General part information

LTC4444 Series

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. 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.The LTC4444 contains undervoltage lockout circuits that disable the external MOSFETs when activated. Adaptive shoot-through protection prevents both MOSFETs from conducting simultaneously.For a similar driver in this product family, please refer to the chart below.ParameterLTC4444LTC4446LTC4444-5Shoot-Through ProtectionYesNoYesAbsolute Max TS100V100V100VMOSFET Gate Drive7.2V to 13.5V7.2V to 13.5V4.5V to 13.5VVCCUV+6.6V6.6V4VVCCUV–6.15V6.15V3.55VApplicationsDistributed Power ArchitecturesAutomotive Power SuppliesHigh Density Power ModulesTelecommunications
