SMBus Timing Data Figure 2. HDQ16 Break Timing Figure 3. HDQ16 Host to bq2060 Figure 4. HDQ16 bq2060 to Host The bq2060 determines battery capacity by monitoring the amount of charge input to or removed from a rechargeable battery. In addition to measuring charge and discharge, the bq2060 measures battery voltage, temperature, and current, estimates battery self-discharge, and monitors the battery for low-voltage thresholds. The bq2060 measures charge and discharge activity by monitoring the voltage across a small-value series sense resistor between the battery’s negative terminal and the negative terminal of the battery pack. The available battery charge is determined by monitoring this voltage and correcting the measurement for environmental and operating conditions. Figure 5 shows a typical bq2060-based battery pack application. The circuit consists of the LED display, voltage and temperature measurement networks, EEPROM connections, a serial port, and the sense resistor. The EEPROM stores basic battery pack configuration information and measurement calibration values. The EEPROM must be programmed properly for bq2060 operation. Table 10 shows the EEPROM memory map and outlines the programmable functions available in the bq2060. 5 |
