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 r_DS(on) power MOSFETs.
The SiP41101 comes with internal break-before-make
circuitry to prevent shoot-through current in the external

MOSFETs. The SD 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_C.
