The IRS25752 is a high-side, single-channel gate driver IC with 600V blocking
and levelshifting capability. This allows for the gate driver to be connected
directly to the gate of a high-side power MOSFET, while being controlled by the
low-side, ground potential circuitry. The IRS25752 includes a wide VCC supply
range, UVLO protection, and excellent immunity to harsh dv/dt or –VS switching
environments. IR’s HVIC technology allows for these functions and features to be
realized in a 6-pin SOT-23 package.

The 600V CoolMOS™ C6 offers a series extremely low conduction and switching
losses and can make switching applications more efficient, more compact, lighter
and cooler.
