ManufacturerName() (0x20); [0x20–0x2a]
Description: This function returns a character array containing the battery manufacturer's name. For example,
MyBattCo would identify the Smart Battery manufacturer as MyBattCo. The bq2060A sets ManufacturerName()
to the value programmed in Manufacturer Name EE 0x20–0x2a.
Purpose: The ManufacturerName() function returns the name of the Smart Battery manufacturer. The
manufacturer's name can be displayed by the SMBus host power-management system display as both an
identifier and as an advertisement for the manufacturer. The name is also useful as part of the information
required to uniquely identify a battery.
SMBus Protocol: Read Block
Output:
String—character string with maximum length of 10 characters (10 + length byte).
DeviceName() (0x21); [0x28–0x2b]
Description: This function returns a character string that contains the battery name. For example, a
DeviceName() of BQ2060A would indicate that the battery is a model BQ2060A. The bq2060A sets
DeviceName() to the value programmed in Device Name EE 0x30–0x37.
Purpose: The DeviceName() function returns the battery name for identification purposes.
SMBus Protocol: Read Block
Output: String—character string with maximum length of 10 characters (10+length byte).
DeviceChemistry() (0x22); [0x30–0x32]
Description:This function returns a character string that contains the battery chemistry. For example, if the
DeviceChemistry() function returns NiMH, the battery pack would contain nickel metal hydride cells. The
bq2060A sets DeviceChemistry() to the value programmed in Device Chemistry EE 0x40–0x44.
Purpose: The DeviceChemistry() function gives cell chemistry information for use by charging systems. The
bq2060A does not use DeviceChemisty() values for internal charge control or fuel gauging.
SMBus Protocol: Read Block
Output: String—character string with maximum length of 4 characters (4+length byte).

ManufacturerData() (0x23); [0x38–0x3a]
Description: This function allows access to the manufacturer data contained in the battery (data). The bq2060A
stores seven critical operating parameters in this data area.
Purpose: The ManufacturerData() function may be used to access the manufacturer's data area. The data fields
of this command reflect the programming of five critical EEPROM locations and can be used to facilitate
evaluation bq2060A under various programming sets. The ManufacturerData() function returns the following
information in order: Control Mode, Digital Filter, Self-Discharge Rate, Battery Low %, Near Full, and the pending
EDV threshold voltage (low byte and high byte.)
