Brief Description

The KTS1685 over-voltage protection device features an

ultra-low 140mΩ (typical) on-resistance high current

integrated MOSFET which actively protects low-voltage

systems from voltage supply faults up to +30VDC. 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 KTS1685 automatically chooses the internal

fixed OVLO threshold, preset to 6.8V (typical). The overvoltage

protection threshold can be adjusted with optional

resistor divider to a voltage between 4V and 22V.

The device features an open-drain output ?A??C??O???K? indicating

a stable supply between the minimum supply voltage and

OVLO threshold. In case of fault condition and the device

temperature exceeds the maximum junction temperature,

the device switches off.

The KTS1685 is available in a RoHS and Green compliant

9-Bump 1.33 x 1.33mm WLCSP.
