A protection circuit for use with an electronic DSL component having a tip connection and a ring connection, the protection circuit including: a first unidirectional transient-voltage-suppression (TVS) diode, having a negative TVS breakdown voltage BDV and diode forward voltage DV clamp, connected between Vcc and the tip connection of the DSL component; a second unidirectional TVS diode, having a diode forward voltage DV, connected between the tip connection of the DSL component and a negative ground clamp node; a third unidirectional TVS diode, having a negative TVS breakdown voltage BDV and diode forward voltage DV clamp, connected between Vcc and the ring connection of the DSL component; and a fourth unidirectional TVS diode, having a diode forward voltage DV, connected between the ring connection of the DSL component and the negative ground clamp node.

Quad TVS protection circuit for an electronic DSL component

Techniques are described for controlling a sensing state of a device. In an example, a controller of the device receives, at a first time, first input data indicating a first request to disable a sensor of the device. The controller causes the sensor to be disabled and stores first data indicating that the sensor is disabled. The device can also include a processor. The controller sends, to the processor, first output data that causes the processor to read the first data from the controller. At a second time, the controller receives second input data indicating a second request for an operation of the device. The controller stores second data associated with the second request and sends, to the processor, second output data that causes the processor to read the second data from the controller.

Maintaining sensing state of a sensor and interfacing with device components

A method for operating a power supply circuit of a communications device involves operating the power supply circuit in a first operating mode in which a switching frequency of the power supply circuit is higher than an operating frequency band of the communications device and switching the power supply circuit to operate in a second operating mode in response to connecting the power supply circuit to a battery by decreasing the switching frequency of the power supply circuit.
