LF2101NTR

Overview

The LF2101NTR is a half-bridge gate driver IC designed to control IGBT and N-channel MOSFET switches in power management applications. It features a floating high-side driver capable of bootstrap operation up to 600V. The device drives two N-channel MOSFETs or IGBTs in a high-side/low-side configuration. Key electrical parameters include a maximum offset voltage of 600V, a typical source peak drive current of 290mA, and a typical sink peak drive current of 600mA. Inputs are designated as HIN and LIN.
