Product Overview

The LTC4442EMS8E#PBF is a high speed high frequency MOSFET Driver designed to drive two N-channel MOSFETs in a synchronous buck DC/DC converter topology. The powerful driver capability reduces switching losses in MOSFETs with high gate capacitance. The LTC4442 features a separate supply for the input logic to match the signal swing of the controller IC. If the input signal is not being driven, it activates a shutdown mode that turns off both external MOSFETs. The input logic signal is internally level-shifted to the bootstrapped supply, which may function at up to 42V above ground. The LTC4442 contains under-voltage lockout circuits on both the driver and logic supplies that turn off the external MOSFETs when an under-voltage condition is present. The LTC4442 has different under-voltage lockout thresholds to accommodate a wide variety of applications. An adaptive shoot-through protection feature is also built-in to prevent power loss resulting from MOSFET cross-conduction current.
