VBUS OVP with a PTVS Diode

RT9746 Feature Product

Update Alert Share

The RT9746 is an overvoltage protection devices feature a low 35mΩ (typ) RON internal FET with PTVS diode. The PTVS also protects the devices from surges up to 100V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected down stream components.

The internal Over Voltage Thresholds (OVP) are preset to 6.8V typical. The RT9746 also feature an over-current protection and up to 4.5A.

The RT9746 is offered in a small WL-CSP-12B (BSC) package provides small PCB area applications.
