Hello,I'm trying to discharge the solid state thin film lithium battery EFL700A39, with a discharge current of 0.7 mA, in the aim of reaching a state of charge of approximately 20%. Actually, the problem is the significant difference of voltages whe...
Hi, In the evaluation board of SPV1050 (STEVAL-ISV020V1), it is mentionned that the maximum voltage from the PV cell (VMP) is to be equal 9V, but there is no indication about the absolute values that I can be supported without damaging the board. I'm...
Hello, this message is addressed to ST employees, if you could please send me additional information not present in the datasheet.I'm using the EFL700A39 rechargeable solid state lithium thin film battery. I'm trying to figure out the state-of-charge...
Hi, I don't know if other people have had this problem.Actually, in the datasheet of the STEVAL-ISV020V1 is mentionned that:R1 = 10 MohmR2= 1 MohmR3 = 5.6 MohmR4 = 6.2 MohmR5 = 500 KohmR6 = 2.7 MohmHowever, when I received my evaluation board, I meas...
Hi, I'm using STEVAL-ISV020V1 the evaluation board for the charge controller SPV1050 ULP. Based on the datasheet, the undervoltage protection (UVP) is 3.7V and the EOC is 4.2V. By doing few changes, VUVP can go down to 2.2 V and VEOC up to 5.3 V. I w...
