Cycle-by-cycle current limiting with latching comparator

WebThe oscillator is programmed with a single resistor to frequencies up to 2MHz. The oscillator can also be synchronized to an external clock. A current sense input and a programmable timer provide cycle-by-cycle current limit and adjustable hiccup mode overload protection. WebThe cycle-by-cycle current-limit truncates the asserted programmed PWM signal (dotted blue lines) when the selected external fault signal is asserted. The PWM output values are specified by the current-limit override bits in one register. The override outputs remain in effect until the beginning of the next PWM cycle. top tech companies in maryland
