Brief Description

The KTS1680A overvoltage protection device features an

ultra-low 28mΩ (typical) on-resistance high current

integrated MOSFET which actively protects 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 overvoltage 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 KTS1680A automatically chooses the internal

fixed OVLO threshold, preset to 5.95V (typical). The overvoltage

protection threshold can be adjusted with optional

resistor divider to a voltage between 4V and 25V.

The device features an open-drain output ̅A̅̅C̅̅O̅̅̅K̅ indicating

a stable supply between the minimum supply voltage and

OVLO threshold. The KTS1680A is also protected against

over-current faults and has thermal protection.

The KTS1680A is available in a RoHS and Green

compliant 12-Bump 1.70mm x 1.21mm x 0.62mm WLCSP.
