Brief Description

The KTS1662 overvoltage protection device features an

ultra-low 26mΩ (typical) on-resistance high current

integrated MOSFET which actively protects low-voltage

systems from voltage supply faults up to +40V.

An input voltage exceeding the overvoltage threshold will

cause the internal MOSFET to turn off, preventing

excessive voltage from damaging downstream devices.

The KTS1662 offers three different fixed OVP options, plus

a fully adjustable option. When the OVLO input is

connected to GND, the KTS1662 automatically chooses

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

Allowing OVLO to float, gives a preset of 10.2V (typical)

and connecting a resistor to GND between 30kΩ and 80kΩ

gives a preset of 13.5V (typical) The overvoltage protection

threshold can also be fully adjusted with an optional

external resistor divider to a voltage between 4V and 28V.

The KTS1662 features a VDET output to indicate the

presence of a voltage at VBUS and is independent of the

OVP switch. In case the device temperature exceeds the

maximum junction temperature, the device switches off.

The KTS1662 is available in a RoHS and Green compliant

12-Bump 1.28 x 1.94 x 0.062mm WLCSP.
