Brief Description

The KTS1650B overvoltage protection (OVP) device

features an ultra-low 36mΩ (typical) on-resistance high

current integrated MOSFET which actively protects lowvoltage

systems from voltage supply faults up to +28VDC.

An internal clamp protects the device from surges up

to 200V.

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 KTS1650B automatically chooses the internal

fixed OVLO threshold, preset to 6.4V (typical). The

overvoltage protection threshold can be adjusted with

optional resistor divider to a voltage between 4V and 24V.

The KTS1650B is protected against over-current faults by

an internal over-temperature protection shutdown feature.

The KTS1650B is available in a RoHS and Green

compliant 12-Bump 2.156mm x 1.486mm x 0.620mm

WLCSP.
