LV8860V no.a1818-8/11 setting value of input signal amplitude the width of soft switch in LV8860V is controlled by input signal, in1/in2. the difference of input voltage ( v in p-p ) that creates width of soft switch is adjustable by ssw voltage (vssw) of an external pin. the range of ssw input voltage is between 1v and 3v. difference of input signal amplitude in vssw range: ? when vssw = 1v (min), v in p-p = 30mv make sure to input hall signal with amplitude difference greater than 30mv. ? when vssw = 2v (open), v in p-p = 90mv make sure to input hall signal with amplitude difference greater than 90mv. ? when vssw = 3v (max), v in p-p = 150mv make sure to input hall signal with amplitude difference greater than 150mv. * when input signal amplitude is greater than v in p-p (as shown in fig. a below). width of soft switch is defined as shown in fig. a * when input signal amplitude is less than v in p-p (as shown in fig. b below). since input signal is within the range of v in p-p in all rotations, the entire zone is the soft switch zone. consequently, ic does not operate properly. for such reason, make sure to input hall signal with e nough amplitude difference to ssw setting value so that ic operates properly. v in p-p =( v in 1 - v in 2 ) in1 in2 v in p-p =( v in 1 - v in 2 ) in1 in2 input signal between soft switches input signal between soft switches fig.a fig.b www.datasheet.co.kr datasheet pdf - http://www..net/
