IR2235JTRPBF Integrated Circuits (ICs)

Power Management ICs (PMICs) are integrated circuits that are used to manage power for both mobile and stationary applications. PMICs have a wide range of applications, and one of their primary functions is to provide gate drivers for power switches. Gate drivers provide a voltage level that helps to activate and deactivate the power switches in electronic systems. In this article, we will discuss the IR2235JTRPBF application field and working principle.

Application Field

The IR2235JTRPBF is an H-bridge gate driver IC designed for use in high power applications. It can be used in combination with power MOSFETs and IGBTs to provide control signal to the gates of the power switches.
