RT9742CGJ5F Description

Short technical summary and product information.

The RT9742CGJ5F is a general-purpose high side power distribution switch designed for applications requiring a single or dual output N-channel switch. It provides a typical on-resistance of 18 mOhm, enabling efficient power delivery with minimal voltage drop. The device supports a load voltage range from 0.8V to 5.5V and is controlled via a simple On/Off interface.

 

This switch includes features such as load discharge and a status flag for fault indication. It is designed for surface mount assembly and is housed in a compact TSOT-23-5 (FC) package, making it suitable for space-constrained designs. The operating temperature range is -40°C to 85°C, allowing use in a variety of environments.

 

Typical applications include power domain switching in portable electronics, load distribution in battery-powered systems, and general power management tasks where a high side switch with low on-resistance is required.
