Texas Instruments BQ28Z610-R2 User Manual

4.1 Introduction
The device can change the values of ChargingVoltage() and ChargingCurrent() based on Temperature() and
Cell Voltage1..2(). Its flexible charging algorithm is JEITA-compatible and can also meet other specific cell
manufacturer charge requirements. The ChargingStatus() register shows the state of the charging algorithm.

4.2 Charge Temperature Ranges
The measured temperature is segmented into several temperature ranges. The charging algorithm adjusts
ChargingCurrent() and ChargingVoltage() according to the temperature range. The temperature ranges set in
data flash should adhere to the following format:
T1 ≤ T2 ≤ T5 ≤ T6 ≤ T3 ≤ T4
