If the voltage at D+ drops any time below 0.325 V SE100 resets the 1.25 seconds timer and stays in USB Battery Charging Specification 1.2 compatibility mode with a default output voltage of 5 V . Once SE100 has entered Quick Charge 2.0 operation mode switch N5 will be turned off. Additionally switch N4 is turned on connecting a 19.53 kΩ pull -down resistor to D -. As soon as the voltage at D- has dropped low (<0.325 V) for at least 1 ms SE100 starts accepting requests for different AC -DC adapter output voltages by means of applied voltage levels at data l ines D+ and D - through the powered device. Table 1 summarizes the output voltage lookup table, corresponding AC -DC adapter output voltages and status of switches N1 to N3. For Quick Charge 2.0 Class A support only, the V3 pin has to be connected to the B YPASS pin (directly or through a resistor up to 100 kΩ). This will inhibit any requests for setting a 20 V output. is pulled down by resistor R DAT(LKG) (see Figure 1). Once it drops below 0.325 V SE100 will turn on switch N5 (thereby short -circuiting D+ and D-) and turns off switches N1 to N4. This sets the default output voltage of 5 V . The recommended value for RDAT(LKG) = 390 kΩ. V o1(5V)=VFB*((R1/R2)+1); Vo2(9V)= VFB*((R1/ RX1)+1), RX1=R2//R3; Vo3(12V)= VFB*((R1/ RX2)+1), RX2=RX1//R4; Vo4(20V)= VFB*((R1/ RX3)+1), RX3=RX2//R5;
