Brief Description

The KTS1693 overvoltage protection device features an

ultra-low 9mΩ (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

±110V.

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 pin input is set below the external OVLO

select voltage, the KTS1693 automatically chooses the

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

The overvoltage protection threshold is adjustable with an

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

The device includes an over-current protection (OCP)

circuit which is programmable via an external resistor.

The open-drain output ?A??C??O???K? indicates a stable supply

between the minimum supply voltage and OVLO threshold.

It also deasserts after 8ms if the switch is in OCP mode

when OC_MODE = Low. In case of a fault condition and

the device temperature exceeds the maximum junction

temperature, the device switches off. The KTS1693-1 has

a VDET pin instead of ?A??C??O???K? pin for VBUS detection

function. VDET pin provides a “clamped” output voltage

whenever a voltage appears on VIN, even if the power

switch is off due to an overvoltage condition.

The KTS1693 is available in a RoHS and Green compliant

20-Bump 2.160 x 1.935mm WLCSP.
