OVER-CURRENT PROTECTION DEVICE

摘要

An over-current protection circuit including, a current supply switch with a first terminal coupled to a supply current input and with a second terminal coupled to a supply current output. The current supply switch is switchable at least between an on-state, in which the current supply switch provides a conductive connection between the first terminal and the second terminal, and an off-state, in which the current supply switch interrupts the conductive connection between the first terminal and the second terminal. The over-current protection circuit receives a supply current via the supply current input and provides the supply current via the supply current output if the switch is in the on-state. The current supply switch includes High Electron Mobility Transistor.

1. An over-current protection circuit comprising:
a supply current input; a supply current output; a current supply switch comprising
a first switch terminal coupled the supply current input,a second switch terminal coupled to the supply current output, anda high electron mobility transistor (HEMT), wherein
the current supply switch provides an on-state, in which the current supply switch provides a conductive connection between the first switch terminal and the second switch terminal, and an off-state, in which the current supply switch interrupts the conductive connection between the first switch terminal and the second switch terminal; and the over-current protection circuit is configured to receive a supply current via the supply current input and to provide the supply current via the supply current output if the current supply switch is in the on-state.
