Working Principle

The RT9702GB is powered by an input voltage, typically 9V to 34V. The IC operates on an internal clock for controlling the switching process. The switching output is provided via an NPN or PNP PFET with a maximum drive current of 200mA. The IC also has an input logic level pin which enables the user to decide whether the output is enabled or disabled.

The IC contains an over-current protection feature. This feature is used to protect loads from an over-current event. When the input current exceeds the maximum allowed, the IC will shut down the output. This feature is especially important for applications where the load is exposed to high current events.

The RT9702GB also includes a thermal protection circuit. This circuit monitors the temperature of the IC and shuts down the output when the temperature exceeds the set threshold. The thermal protection circuit ensures that the IC does not overheat and will protect the load from damage.

The IC also provides an over-voltage protection feature. This feature is used to protect the load from an over-voltage event. When the input voltage exceeds the set limit, the IC will shut down the output. This feature is especially important for applications where the load is exposed to high voltage events.

The RT9702GB is an advanced power switching device which is highly efficient and cost effective. It is ideal for applications that require high performance and efficiency. The IC provides efficient protection against over-current and over-voltage events, and comes with a thermal protection circuit. The IC is easy to use and configure, making it ideal for applications such as power converters, relays, and LED drive.
