Fig.7 Lock protection timing chart *BA6423AF returns normal operation by the input of hall signal during Toff. 2) Hall input setting Hall input voltage range is shown in operating conditions. Fig.8 Hall input voltage range Adjust the value of hall element bias resistor R1 in Fig.9 so that the input voltage of a hall amplifier is input in "hall input voltage range" including signal amplitude.
