Load switch with true reverse current blocking

摘要

Devices, systems and methods are provided for switching a load with true reverse current blocking (TRCB). The device may include an input port coupled to a supply voltage; an output port coupled to the load; a TRCB circuit coupled to the input port and the output port; and a switch control port coupled to the TRCB circuit. The TRCB circuit may be configured to couple the input port to the output port in response to a switch close signal applied to the switch control port and to de-couple the input port from the output port in response to a switch open signal applied to the switch control port. The TRCB circuit may further be configured to block current flow from the output port to the input port in response to both the switch open signal and the switch close signal.
