  • Semiconductor devices and methods for dead time optimization by measuring gate driver response time
    Patent number: 10003260
    Abstract: Switching control devices and related operating methods are provided. An exemplary electronic device includes a semiconductor die, a driver arrangement on the semiconductor die to generate a switch control output signal based on an input switching command signal, and a timer arrangement on the semiconductor die and coupled to the driver arrangement to measure a time difference between a first change in the command signal and an exhibited response in the switch control signal, which can then be utilized to achieve a desired dead time.
    Type: Grant
