Abstract
An overcurrent protection circuit includes: a sense signal generation circuit configured to generate a sense signal according to a current to be monitored; a count completion value setting circuit configured to set a count completion value according to results of comparisons between a second sense signal corresponding to the sense signal and threshold values; and a counter configured to count up a count value when the current to be monitored is greater than a count start threshold value, and to forcibly stop the current to be monitored when the count value reaches the count completion value.
Claims10
An overcurrent protection circuit comprising:
- a sense signal generation circuit configured
- to generate a sense signal according to a current to be monitored;
- a count completion value setting circuit configured
- to set a count completion value according to results of comparisons between the sense signal or a signal corresponding thereto and a plurality of threshold values;
- and
- a counter configured
- to count up a count value when the current to be monitored is greater than a count start threshold value, and
- to forcibly stop the current to be monitored when the count value reaches the count completion value.
