Brief Description

The KTS1675A over-voltage protection device features

high current integrated N-Channel MOSFETs with an ultralow

IN to OUT on-resistance of 25mΩ (typical). Lowvoltage

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) and also

supports reverse bias blocking, preventing any voltage

present at OUT pin feeding back into IN when the device is

in the Off state.

The KTS1675A also features additional protection

including enhanced ESD and thermal to protect against

over-load conditions.

The device is available in a RoHS and Green compliant

20-bump, 0.4mm pitch, 2.22mm x 1.82mm WLCSP.
