KF2031 is an innovative over voltage protector which can be used either in unidirectional or bidirectional mode，by only change the extemal connecting. In bidirectional mode, the switch integrated in KF2031 can shut off with the reverse blocking function, no body diode anymore.

KF2031 consists of a charge pump ,a configurable power MOSFET, a voltage reference, a gate driver and some logics and protection modules. KF2031 can react to a input surge very fast and shut off the switch in 0.5us and stand the voltage spike as high as 20V.

KF2031 is in SOT-23-6 package.

  FEATURES

Unidirectional and Bidirectional configurable

Input OVP with 0.1us reaction time

Input standoff voltage up to 20V

10mohm Rdson in Unidirectional mode

40mohm Rdson in Bidirectional mode

Protection voltage programmable by Vfb=1.26V

SCP and OTP

  Application

All electronic devices with input DC power plug
