Latest Patents
One of Haglan's latest patents is for a low quiescent current low-dropout regulator (LDO). This innovative LDO regulator includes a first transistor coupled between an input voltage node and an output voltage node. It features a first amplifier that controls the gate of the first transistor, along with a feedback path that connects the output voltage node to the input of the first amplifier. Additionally, a second amplifier is included, which is responsible for enabling the first amplifier through a voltage-sensing path. The design also incorporates a second transistor that connects the gate of the first transistor to a reference potential node.
Another significant patent by Haglan is a switching system that allows primary USB connection in response to USB signaling. This system controls connectivity within a device that may be coupled to a host device. The low power logic of the device can perform enumeration with the host device using only the power provided by the host. Furthermore, it can charge the device's battery while maintaining connectivity and performing device enumeration.
