Product Summary
The LTC4440EMS8E#TR is a high frequency high side N-channel MOSFET gate driver that is designed to operate in applications with VIN voltages up to 80V. The LTC4440EMS8E#TR can also withstand and continue to function during 100V VIN transients. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitances. The LTC4440 contains both high side and low side undervoltage lockout circuits that disable the external MOSFET when activated. The LTC4440EMS8E#TR is available in the low profile (1mm) SOT-23 or a thermally enhanced 8-lead MSOP package. The applications of the LTC4440EMS8E#TR are (1)telecommunications power systems; (2)distributed power architectures; (3)server power supplies; (4)high density power modules.
