11 / 37 page L8150 Electrical characteristcs 11/37 l Note: 1 If 20mA is a problem for design because of power dissipation etc., it can be reduced to something like 5mA 2 one input is set at 2.5V by means of a resistor divider. The other input moves from 0V to Vreg. The Hall comparator must operate correctly for all its input range. 3 Opamp need to be designed to meet with Kval control by VSP. External circuit for Vsp control (example) is shown in following Figure 4. The tolerance at Vsp including external resistor (E96) is as follows: mini typ max V1(V) 0.85 1.23 1.6 V2(V) 1.7 2.1 2.5 V3(V) 4.9 5.4 6.1 4 FR and INTin+ are used to set test mode as follows: Test mode is set by 8 events (clock rising edges) on FR during INTin+>4.5 (Power is kept as high-impedance for INTin+ > 4.5 until 7th event occur) (counter for FR is reset by INTin+ < 4.5) Table 16.
