Notes
a. Device mounted with all leads soldered or welded to PC board.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.




Description

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.

The SiP41101 comes with internal break-before-make circuitry to prevent shoot-through current in the external MOSFETs. TheSD control pin is provided to enable the drivers. A Synchronous Enable control pin is provided to disable the the low-side or synchronous MOSFET to maximize efficiency under low output current conditions.

The SiP41101 is available in a 16-pin TSSOP package for operation over the industrial temperature range of -40 to 85 .
