Note:

(1) The condition can be achieved with the test circuit only. The Current Accuracy may be affected by negative temperature

coefficient and inappropriate package.

(2) For HM7230/HM7235/HM7240/HM7245 high current applications, it is necessary to add a heat sink to lower the case

temperature to below 50oC to guarantee the current accuracy of ±3%.
