  • Master slave charging architecture with communication between chargers
    Patent number: 10396582
    Abstract: A battery charging system includes a master charger that receives a supply voltage, outputs a master charging current based on the supply voltage, and selectively outputs a slave charger control signal. At least one slave charger receives the slave charger control signal from the master charger, receives the supply voltage, and selectively outputs a slave charging current based on the slave charger control signal and the supply voltage.
    Type: Grant
    Filed: June 30, 2016
    Date of Patent: August 27, 2019
    Assignee: Maxim Integrated Products, Inc.

  • Power management systems with charge pumps
    Patent number: 9018917
    Abstract: A driving circuit for an N-channel Metal Oxide Semiconductor (NMOS) transistor can include a charge pump unit and a driver coupled to the charge pump. The charge pump can receive a source voltage and output an output voltage higher than the source voltage, where the source voltage is applied to a source terminal of the NMOS transistor. The driver receives the output voltage of the charge pump unit and converts the output voltage to a driving voltage operable for conducting the NMOS transistor.
