RT9742EGJ5F Description

Short technical summary and product information.

The Richtek RT9742EGJ5F is an N-Channel power distribution switch suitable for load driving applications. It operates with a load voltage range of 2.7V to 6V and can deliver a maximum output current of 1.5A. The switch features a low typical RdsOn of 55mOhm, contributing to efficient power management.

 

Key electrical characteristics include its non-inverting input type and On/Off interface. The device incorporates fault protection mechanisms such as fixed current limiting, over-temperature protection, reverse current protection, and UVLO (Under-Voltage Lockout). It also includes features like load discharge and a status flag.

 

This power switch is housed in a compact TSOT-23-5 (FC) surface-mount package, making it suitable for space-constrained designs. The operating temperature range is -40°C to 85°C (TA). The device is classified as a USB Switch and has a 1:1 ratio for input to output.

 

Environmental compliance includes RoHS3 compliance and an MSL 1 rating. The REACH status is unaffected.
