Abstract
The disclosure relates to a device and a circuit for protecting controlled loads, and an apparatus for switching between the loads. The device includes: a plurality of load switches, comprising at least first and second load switches, wherein the first and second load switches are respectively in series connection with first and second controlled loads to form first and second controlled load branches in parallel connection, and each load switch is turned on when a switch control terminal is in a first voltage/current interval and turned off when the switch control terminal is in a second voltage/current interval; and a signal control module, including a signal control element, wherein the signal control element is switched between the switch control terminals of the first and second load switches for connection, and the signal control element enables, when being connected to the switch control terminal, the corresponding switch control terminal to be in the second voltage/current interval, and enables, when being disconnected from the switch control terminal, the corresponding control terminal to be in the first voltage/current interval.
