SiP41108

SIP41101 : 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. The SD control pin is provided to enable the drivers. A Synchronous Enable control pin is provided to disable the the low-side or sync.

SiP41103 : SiP41103 is a high-speed half-bridge MOSFET driver with adaptive shoot-through protection for use in high frequency, high current, multiphase dc-dc synchronous rectifier buck power supplies. It is designed to operate at switching frequencies up to 1 MHz. The high-side driver is bootstrapped to allow driving n-channel MOSFETs. SiP41103 comes with adaptive shoot-through protection to prevent simultaneous conduction of the external MOSFETs. The SiP41103 is available in both standard and lead (Pb)-free 10-Pin MLP33 packages and is specified to operate over the industrial temperature range of −40 _C to 85 _C.

SIP41109 : The SiP41109 and SiP41110 are high-speed half-bridge MOSFET drivers for use in high frequency, high current, multiphase dc-to-dc synchronous rectifier buck power supplies. They are designed to operate at switching frequencies up to 1 MHz. The high-side driver is bootstrapped to allow driving n-channel MOSFETs. They feature adaptive shoot-through protection to prevent simultaneous conduction of the external MOSFETs. There are two options available for the voltage of the high-side and low-side drivers. In the SiP41109, the regulator supplies gate drive voltage to the high-side driver and VCC supplies the low-side driver. in the SiP41110, the regulator supplies the high- and low-side gate drive.
