LTC7065RMSE#PBF

LTC7065RMSE#PBF is a half-bridge dual N-channel MOSFET gate driver that operates at up to 100V input voltage and features a supply-independent three-state PWM input logic. The strong 1.3ohm pull-down and 1.6 ohm pull-up drive capability can drive large gate capacitances of high voltage MOSFETs with short transition times in high switching frequency applications. The adaptive shoot-through protection is designed for optimized efficiency and MOSFET cross-conduction protection. It contains Undervoltage lockout circuits on both the VCC supply and floating driver supply that turn off the external MOSFETs when activated. It is used in applications such as industrial power systems, half-bridge DC/DC converters, and telecommunication power systems.
