The Richtek RT9728AHZQW is a high-side P-channel power distribution switch designed for USB applications. It offers a 1:1 input to output ratio and supports load voltages from 2.5V to 5.5V, with a maximum output current of 1.3A.
Key electrical specifications include a typical Rds On of 120mOhm. The device integrates features such as a status flag, adjustable current limiting, over-temperature protection, and undervoltage lockout (UVLO) for robust operation. It operates within a temperature range of -40°C to 85°C.
This component is housed in a compact 6-WDFN (2x2) package with an exposed pad, suitable for surface mounting. The non-inverting input and On/Off interface simplify integration into various designs.
Environmental compliance includes RoHS3 compliance and an MSL rating of 3. The REACH status is unaffected.
