The STBP110 is an overvoltage protection device produced by STMicroelectronics. It features input overvoltage protection, soft-start, low RDS(on), maximum continuous current of 1.2A, thermal shutdown, TDFN 8-lead package, etc. It is used in smart phones, digital cameras, PDAs and palmtop devices, MP3 players and low power handheld devices.
The STBP110 is an overvoltage protection device designed to protect systems connected to the OUT pin against failures of DC power supplies. It features an integrated high voltage N-channel MOSFET switch with a low on-resistance of 170 mΩ and an integrated charge pump. The device offers input overvoltage protection up to 28 V and includes thermal shutdown and soft-start features to control inrush current.
The STBP110 is available in a small, RoHS-compliant 2 x 2 x 0.75 mm TDFN 8-lead package with a thermal pad. It is suitable for applications in smart phones, digital cameras, PDA and palmtop devices, MP3 players, and other low power handheld devices. The device provides fault indication via an open-drain output and can be controlled by a microcontroller.
