Brief Description

The KTS1671 over-voltage protection device features an

ultra-low 60mΩ (typical) on-resistance high current

integrated MOSFET which actively protects low-voltage

systems from voltage supply faults up to +28V.

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 is connected to GND, the KTS1671

automatically chooses the internal fixed OVLO threshold,

preset to 6.15V (typical). The over-voltage protection

threshold can be adjusted with an optional external resistor

divider to a voltage between 4V and 20V.

In case the device temperature exceeds the maximum

junction temperature, the device switches off.

The KTS1671 is available in a RoHS and Green compliant

6-Bump 1.20 x 1.00mm WLCSP.
