RT9746
RT9746 is VBUS OVP manufactured by Richtek.
Description
The RT9746 is an over-voltage 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 over-voltage threshold, the internal FET is turned off to prevent damage to the protected down stream ponents.
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.
