ETA4034 - Li+ Charger Front-End Protection

Datasheet Summary

Features

  • ETA4034 is an over-voltage protection(OVP) and overcurrent protection(OCP) IC with NTC. The OVP function includes Input OVP and Battery OVP(BVOVP). The input OVP can sustain input voltage as high as 30V, protecting downstream devices from high voltage surge. When input voltage of ETA4034 exceeds the input OVP threshold, it responses quickly and shuts off the MOSFET. The OVP threshold 6.15V is fixed internally. When Battery voltage at ETA4034 BAT pin exceeds the BVOVP threshold, it also response.
