A portable communications device is disclosed that comprises a plurality of wireless backhaul connections to a public network and a mobile mesh network connection for establish a wireless local area network. Description: Product Details The LTC3559/LTC3559-1 are USB battery chargers with dual high efficiency buck regulators. I recommend using either the radio test example or alternately direct test mode.Both implement this already and can be found in the SDK under nRF5SDK11.0.089a8197examplesperipheralradiotest and nRF5SDK11.0.089a8197examplesdtmdirecttestmode. A power distribution unit (PDU) is disclosed for a rechargeable battery system that supplies power to a plurality of devices each having a different voltage requirement The PDU comprises a plurality of DC/DC converters for converting a first DC value to a plurality of DC levels, wherein each of the plurality of DC levels are associated with a different one of the voltage requirements. SOLUTION: A totem pole output stage 10 includes 1st and 2nd control modules 12 and 16 which are cross-connected to the 1st and 2nd switching modules 14 and 18. The STUSB4500L from STMicroelectronics is a small-footprint addition to the Company’s USB-C controller IC family designed and certified for pure 5V sink-only. PROBLEM TO BE SOLVED: To provide a totem pole output stage which does not use time delay to generate any mutual conductive events and also minimizes the switching time.
A controller for a rechargeable battery system is disclosed that evaluates whether a cover of the rechargeable battery system is open or closed determines whether an AC power source is available evaluates a charge level (for example, from a system management bus) of one or more batteries in the rechargeable battery system and enables a charging circuit for one or more batteries requiring a charge based on whether the cover of the rechargeable battery system is open or closed and if the AC power source is available A charging circuit for the rechargeable battery system is disclosed that comprises one or more programmable voltage sources for charging one or more batteries in the rechargeable battery system. thing is set to, the undecided, but no doubt useful for charging/tickling ALMOST any battery i've ever seen, maybe with a totem/push+pull output end so it can un-charge stuff also, and of course the not GIANT, but not avg kinda bench supply voltage and current capable single variable, you know, maybe 0-50v at up to 4 or 5A, whatever seems to. Standalone VBUS-Powered Controller for 5V USB-C Charging Applications.
