  • Low cost power line modem
    Patent number: 11750243
    Abstract: A system for transmitting power and data through a two pin connection interface may have a first device having a power source, a first microcontroller with a first communication peripheral coupled with a first pin and a first control port coupled with a gate of a first MOSFET whose switch path couples the power source with the first pin; and a second device having a battery, a second microcontroller with a second communication peripheral coupled with a first pin and a second control port coupled with a gate of a second MOSFET whose switch path couples the battery with the first pin of the second device. When the devices are coupled, the MOSFETs are synchronously turned on and off, wherein during an off-cycle a data transfer between the first and second device takes place through the first and second communication peripherals of the first and second device, respectively.
