Hello,
I’ve read this tutorial 2: How To Make IP5306 Battery Management Circuit
Looking at referred datasheet there is a slight difference with the datasheet on the official site.
Note that pin 6 (BAT sensor), in the official site document, is connected to the battery through resistor R4. But in the datasheet used in this tutorial pin 6 (BAT) is connected directly to the battery. Also, the values of of C2, C7 and R4 are not exactly the same.
I’ve designed a handheld device that uses the ip5306 according to the schematic of the official document. (ESP32+RFIDSensor+IP5306). Everything works fine except the battery sensing.
LED 4 (Full 100%) never stops blinking while charging. LEDs wiring is OK and battery is OK (fully charged on another charger).
My questions are,
-where was this datasheet obtained from?
-this difference in wiring could be the cause of the problem?
I ordered the printing of 5 PCBs and I need to fix the error before printing again.
Thanks in advance,
Osmany
