Hot-selling and scarce LTC4446EMS8E-PBF Half-Bridge Gate Driver IC Non-Inverting 8-MSOP-EP spot stock
LTC4446EMS8E#PBF Half-Bridge Gate Driver IC Non-Inverting 8-MSOP-EP spot stock
Product Descriptions
The LTC®4446 is a high frequency high voltage gate driverthat drives two N-channel MOSFETs in a DC/DC converterwith supply voltages up to 100V. The powerful driver capability reduces switching losses in MOSFETs with highgate capacitance . The LTC4446’s pull-up for the top gatedriver has a peak output current of 2.5A and its pull-downhas an output impedance of 1.2Ω.The pull-up for the bottom gate driver has a peak output current of 3A and thepull-down has an output impedance of 0.55Ω.
The LTC4446 is configured for two supply-independentinputs . The high side input logic signal is internallylevel-shifted to the bootstrapped supply, which mayfunction at up to 114V above ground .
The LTC4446 contains undervoltage lockout circuits thatdisable the external MOSFETs when activated .
The LTC4446 is available in the thermally enhanced 8-leadMSOP package .
The LTC4446 does not have adaptive shoot-through protection . For similar drivers with adaptive shoot-throughprotection, please refer to the chart below.
