发明名称 NOISE IMMUNE OVER CURRENT PROTECTION WITH INHERENT CURRENT LIMITING FOR SWITCHING POWER CONVERTER
摘要 A circuit for providing over-current protection, the circuit including a gate driver circuit for controlling a bridge circuit including a half bridge stage having high and low switches. The circuit includes a feedback loop circuit for counting over-current indicators sensed during one or more consecutive PWM cycles; wherein when an over-current indicator is sensed, the low switch is turned OFF for duration of a first time period after which the low switch is turned back ON, to enable determination of an over-current condition where false noise signals are rejected thereby preventing circuit shutdowns due to false over-current condition.
