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 ̅A̅̅C̅̅O̅̅̅K̅ 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 ̅A̅̅C̅̅O̅̅̅K̅ 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.
