The SiP41101 is a high speed half-bridge driver, with make-before-break, for use in high frequency, high current multiphase dc-to-dc power supplies for supply voltages as high as 30 V. It is designed to operate at frequencies up to 1 MHz. The high-side driver is bootstrapped to allow driving an n-channel high-side MOSFET. The bootstrap diode is internal. The output drivers provide currents up to 4 A, allowing use of low rDS(on) power MOSFETs.
