Brief Description

The KTS1682 over-voltage protection (OVP) device

features an ultra-low 38mΩ (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

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 KTS1682 automatically chooses the internal

fixed OVLO threshold, preset to 9.98V (typical). The overvoltage

protection threshold can be adjusted with optional

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

The device features a microphone mode which disables

the OVP switch and allows the microphone signal present

on the input to be output at VDET pin without an additional

multiplexer circuit. The KTS1682 is protected against overcurrent

faults by an internal over-temperature protection

shutdown feature.

The KTS1682 is available in a RoHS and Green compliant

12-Bump 1.288mm x 1.988mm x 0.64mm WLCSP
