Overvoltage Protector with Bidirectional Blocking and Surge Protection
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.
