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.
