Hi,
We have the BQ20Z655R1 - Battery Management IC and use the 5 segment bargraph lcd to display the state of charge. Single bar corresponds to 20% of the fuel gauge.
The fuel gauge is beetween %0 and %20, 1th segment is enabled, the others are disabled as it should.
The fuel gauge is beetween %21 and %40, 1th and 2nd segment are enabled, the others are disabled as it should.
The fuel gauge is beetween %41 and %60, 1th, 2nd and 3th segments are enabled, the others are disabled as it should.
The fuel gauge is beetween %81and %100, all of the segments are enabled as is should.
But when the fuel gauge is between 61% and 80%, 5th segment is enabled too. It should be disabled. We use typical LCD implementation with 330k pull up resistor in the BQ20Z655-R1 datasheet of TI.
Best Regards,
Thank you for your help in advance.
John.
