STMicroelectronics STBP Voltage Protection ICs
STMicroelectronics STBP Voltage Protection ICs provide overvoltage protection for input voltage up to +28V. The low RDS(on) N-channel MOSFET switch protects the systems connected to the OUT pin against failures of the DC power supplies. 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, these STMicroelectronics STBP Voltage Protection ICs also monitor their junction temperature and switch off the internal MOSFET if the junction temperature exceeds the specified limit. Each device can be controlled by a microcontroller and can also provide status information about fault conditions.
