Description
The STBP120 device provides overvoltage protection for input voltage up to +28 V. Its low
R
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 R
to protected systems.
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 STBP120 is offered in a small, RoHS-compliant TDFN – 10-lead (2.5 mm x 2 mm)
package.
