RT9746

VBUS OVP with a PTVS Diode

General Description

Features

^PTVS Diode Embedded for VBUS Surge Protection

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 components.

^Warning Indicator for OVP or UVP

^28V Maximum Rating for DC Adapter

^Integrated Over-Voltage and Over-Current

Protection FET on VBUS for Fault Isolation

Applications

 Cellular Phone

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.

 Smart HandheldDevice

The RT9746 is offered in a small WL-CSP-12B (BSC)

package provides small PCB area applications.
