  • 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.

  • Spindle speed detection through current sensing during boost braking
    Patent number: 8781786
    Abstract: A circuit includes a comparator having input terminals configured to be coupled across a drive transistor adapted to drive a phase of a motor. The comparator senses a drive current of the motor phase, said sensed drive current represented by a periodic signal whose period is indicative of motor speed. A motor speed calculation circuit receives the periodic signal and processes the periodic signal to determine a speed of the motor.
