LTC4446
Key Features
- n n n n n n n n n n n n - LTC4446 High Voltage High Side/ Low Side N-Channel MOSFET Driver DESCRIPTION
- 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
