Hello,
I have a customer interested in using the BQ2060A as a gas gauge only. A separate battery charger would be used to control the charging of the battery so he would want to disable the charge control feature as detailed below (p.14 of datasheet). No EEPROM, no temperature monitoring would be used either. What would be the recommended register settings for this and any I/O termination required for unsed pins- ie. ESCL, ESDA, thermistor pins, etc?
Charge Control
Charging Voltage and Current Broadcasts Charging Voltage and Current Broadcasts The bq2060A supports SBS charge control by broadcasting the ChargingCurrent() and ChargingVoltage() to the Smart Charger address. The bq2060A broadcasts the requests every 10 s. The bq2060A updates the values used in the charging current and voltage broadcasts based on the battery state of charge, voltage, and temperature. The fast-charge rate is programmed in
Fast-Charging Current EE 0x1a–0x1b while the charge
voltage is programmed in
Charging Voltage EE 0x0a–0x0b. The bq2060A internal charge control is compatible with popular rechargeable chemistries. The primary
charge-termination techniques include a change in temperature over a change in time (
