G5288QE1D

The G5288B is an integrated, cost-effective, electronic fuse optimized for monitoring output current and input voltage. Connected in series to a 5V power-rail, it is capable of protecting the electronic circuitry on its output from over current and overvoltage during output load transient and input voltage transient. If a continuous short-circuit is present on the board, when power is re-applied, G5288B initially limits the output current to a safe value to lower the power on G5288B and a thermal protection circuit is integrated as well. There is no degradation on G5288B after short-circuit/thermal protection events and it is reset either by recycling the supply voltage or using the En/Fault pin. G5288B also has a programmable delay to control turn on time.
