SANKEN SSC4S790
High-side Gate Driver IC
SSC4S790
Data Sheet
Description
SSC4S790 is a single channel high-side gate driver.
The IC incorporates a floating drive circuit for a high-
side power MOSFET, which can be used for a high-side
gate driver such as a half-bridge converter or bridgeless
PFC.
The IC is provided in the compact and low profile
SOIC8 package.

1. Absolute Maximum Ratings
Current polarities are defined as follows: current going into the IC (sinking) is positive current (+); current coming
out of the IC (sourcing) is negative current (). Unless otherwise specified, TA = 25 °C. Surge withstand capability
(HBM) of the SSC4S790 is guaranteed up to 2000 V. Note that the following pins are guaranteed to withstand surges up
to 1000 V: 5, 6, 7.
