Brief Description

The KTS1680C overvoltage protection device features an
ultra-low 28mΩ (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 100V.
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 KTS1680C automatically chooses the internal
fixed OVLO threshold, preset to 6.3V (typical). The
overvoltage protection threshold can be adjusted with
optional resistor divider to a voltage between 4V and 25V.
The device features an open-drain output ̅A̅̅C̅̅O̅̅̅K̅ indicating
a stable supply between the minimum supply voltage and
OVLO threshold. The KTS1680C is also protected against
over-current faults and has thermal protection.
The KTS1680C is available in a RoHS and Green
compliant 12-Bump 1.70mm x 1.21mm x 0.62mm WLCSP.
