Other Parts Discussed in Thread: BQSTUDIO
Hello TI team,
I am setting up the initial values for the BQ27220 and in the TRM (SLUUBD4) it mentions Taper Voltage (section 4.9.47 page 59) yet I do not see a memory address for it. If I can't change the value and I don't know what the value is then how can I be certain the device will meet one of the three (3) requirements for Primary Charge Termination detection as specified in the TRM?
Requirements for Primary Charge detection:
1. During two consecutive periods of Current Taper Window, the Current() is < Taper Current.
2. During the same periods, the accumulated change in capacity > 0.25 mAh per Current Taper Window.
3. Voltage() >Charging Voltage – Taper Voltage.
Additionally - the TRM keeps referring to the BIEnable (battery Insertion enable) bit is in Operation Config B (see section but table 4.1.2 Operation Configuration A (Operation Config A) Register indicates the BIEnable is in LOW BYTE bit [7]. Which is correct?
Respectfully,
Keith Haydon
