Brief Description

The KTS1686 over-voltage protection device features high

current integrated N-Ch MOSFETs with an ultra-low IN to

OUT on-resistance of 65mΩ (typical), actively protecting

low-voltage systems from voltage supply faults up to

+28VDC. An internal clamp protects the device from

surges up to +100V.

An input voltage exceeding the over-voltage threshold will

cause the internal MOSFET to turn off, preventing

excessive voltage from damaging downstream devices.

When the OVLO input set below the external OVLO select

voltage, the KTS1686 automatically chooses the internal

fixed OVLO threshold, preset to 5.885V (typical). The overvoltage

protection threshold can be adjusted with optional

resistor divider to a voltage between 5V and 22V.

The KTS1686 also features reverse bias blocking,

preventing any voltage present at OUT not feeding back

into IN when the device is in the OFF state. When OTG_EN

is high, the path from OUT to IN is enabled, to permit the

powering of external OTG peripherals.

The KTS1686 also features additional protection including

enhanced ESD protection and thermal protection to protect

against over-load conditions.

The KTS1686 is available in a RoHS and Green compliant

15-Bump 1.6mm x 2.1mm WLCSP.
