Kinetic Technologies KTS1675A Over-Voltage Protection IC

Kinetic Technologies KTS1675A Over-Voltage Protection IC features high current integrated N-Channel MOSFETs with an ultra-low IN to OUT on-resistance of 25mΩ (typical). Low voltage systems on the output are protected from voltage supply faults up to +28V. An internal clamp on the input protects the device from surges up to ±100V. An input voltage exceeding the over-voltage threshold causes the internal MOSFETs to turn off, preventing excessive voltage from damaging downstream devices.

The KTS1675A has a selectable internal fixed OVLO threshold preset to either 13V or 23.4V (typical). Also, it supports reverse bias blocking, preventing any voltage present at OUT pin feeding back into IN when the device is in the Off state.

The Kinetic Technologies KTS1675A also features additional protection, including enhanced ESD and thermal to protect against overload conditions. The device is available in a RoHS and Green compliant 20-bump, 0.4mm pitch, 2.22mm x 1.82mm WLCSP.
