Description

The LTC4440-5 is a high frequency high side N-channel MOSFET gate driver that is designed to operate in applications with VINvoltages up to 60V. The LTC4440-5 can also withstand and continue to function during 80V VINtransients. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitances. The LTC4440-5’s pull-up has a peak output current of 1.1A and its pull-down has an output impedance of 1.85Ω.The LTC4440-5 features supply independent TTL/CMOS compatible input thresholds with 350mV of hysteresis. The input logic signal is internally level-shifted to the bootstrapped supply, which may function at up to 95V above ground.The LTC4440-5 is optimized for driving (5V) logic level FETs and contains an undervoltage lockout circuit that disables the external MOSFET when activated.The LTC4440-5 is available in the low profile (1mm) SOT-23 or a thermally enhanced 8-lead MSOP package.ParameterLTC4440-5LTC4440A-5LTC4440Max Operating TS60V80V80VAbssolute Max TS80V100V100VMOSFET Gate Drive4V to 15V4V to 15V8V to 15VVCC UV+3.2V3.2V6.3VVCC UV-3.04V3.04V6.0VApplicationsTelecommunications Power SystemsDistributed Power ArchitecturesServer Power SuppliesHigh Density Power ModulesGeneral Purpose Low-Side Driver
