Brief Description

The KTS1675 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 KTS1675 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 KTS1675 also provides a selectable,
always ON, clamped output voltage of 16V or 20V max.
The KTS1675 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.
