MOSFET High side and low side drivers

[Vicky]

Hi,
I would like to know what is the difference between MOSFET High side
and low side drivers.Are there any good documents available for
developing spice models for these?

: One is PMOS the other is NMOS

There are NMOS high side with charge pumps

Hi,
I would like to know what is the difference between MOSFET High side
and low side drivers.

The high side drivers (those designed for driving N-channel high-side
MOSFETs) are often more complex with a bootstrap supply and level
translation in addition to the buffer function. The low side drivers
are more or less just a buffer, perhaps with low-voltage inhibit
and/or deadtime circuitry.
