DESCRIPTION The Si P41109 and Si P41110 are high-speed half-bridge low-side drivers. In the Si P41109, the regulator supplies gate MOSFET drivers for use in high frequency, high current, drive voltage to the high-side driver and VCC supplies the multiphase dc-to-dc synchronous rectifier buck power low-side driver. in the Si P41110, the regulator supplies the supplies. They are designed to operate at switching high- and low-side gate drive voltage. frequencies up to 1 MHz. The high-side driver is bootstrapped
to allow driving n-channel MOSFETs. The Si P41109 and Si P41110 are assembled in a lead (Pb)-free 8-pin SOIC package for operation over the

Frequently Asked Questions
What protection prevents simultaneous conduction of external MOSFETs?
Adaptive shoot-through protection is utilized to prevent the simultaneous conduction of external MOSFETs.
What is the specified operating temperature range?
The recommended operating temperature range is -40 to 85°C.
What type of DC/DC conversion are these drivers designed for?
They are high-speed half-bridge low-side drivers used for high current, low voltage DC/DC converters.
How does the device handle overheating?
If the die temperature rises above 165°C, Thermal Protection disables the drivers and re-enables them after it drops below 140°C.
