Description

General part information

LTC4446 Series

The LTC4446 is a high frequency high voltage gate driver that drives two N-channel MOSFETs in a DC/DC converter with supply voltages up to 100V. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitance. The LTC4446’s pull-up for the top gate driver has a peak output current of 2.5A and its pull-down has an output impedance of 1.2Ω. The pull-up for the bottom gate driver has a peak output current of 3A and the pull-down has an output impedance of 0.55Ω.The LTC4446 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 LTC4446 contains undervoltage lockout circuits that disable the external MOSFETs when activated.The LTC4446 is available in the thermally enhanced 8-lead MSOP package.The LTC4446 does not have adaptive shoot-through protection.
