Brief Description

The KTS1676 over-voltage protection device features high

current integrated N-Channel MOSFETs with an ultra-low

IN to OUT on-resistance of 20mΩ (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 KTS1676 has a selectable internal fixed OVLO

threshold preset to either 13V or 17V (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 KTS1676 also provides a selectable,

always ON, clamped output voltage of 16V or 20V max.

The KTS1676 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.
