Description

The STBP110 device provides overvoltage protection for input voltage up to +28 V. Its low

RDS(on) N-channel MOSFET switch protects the systems connected to the OUT pin against

failures of the DC power supplies in accordance with the China MII Communications

Standard YD/T 1591-2006.

In the event of an input overvoltage condition, the device immediately disconnects the DC

power supply by turning off an internal low RDS(on) N-channel MOSFET to prevent damage

to protected components.

In addition, the device also monitors its own junction temperature and switches off the

internal MOSFET if the junction temperature exceeds the specified limit.

The device can be controlled by the microcontroller and can also provide status information

about fault conditions.

The STBP110 is offered in a small, RoHS-compliant 8-lead TDFN (2 mm x 2 mm) package.
