command codes (continued)
ManufacturerName( ) (0x20); [0x20-0x25]
Description: This function returns a character array containing the battery’s manufacturer’s name. For
example, MyBattCo identifies the Smart Battery’s manufacturer as MyBattCo. The bq2063 sets
ManufacturerName( ) to the value programmed in Manufacturer Name EE 0x20-0x2b.
Purpose: The ManufacturerName( ) function returns the name of the Smart Battery’s manufacturer. The
manufacturer’s name can be displayed by the SMBus Host’s 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 11 characters (11 + length byte).
DeviceName( ) (0x21); [0x28-0x2b]
Description: This function returns a character string that contains the battery’s name. For example, a
DeviceName( ) of bq2063A indicates that the battery is a model bq2063A. The bq2063 sets DeviceName( ) to
the value programmed in Device Name EE 0x30-0x37.
Purpose: The DeviceName( ) function returns the battery’s name for identification purposes.
SMBus Protocol: Read Block
Output: String-character string with maximum length of 7 characters (7 + length byte).
DeviceChemistry( ) (0x22); [0x30-0x32]
Description: This function returns a character string that contains the battery’s chemistry. For example, if the
DeviceChemistry( ) function returns NiMH, the battery pack contains nickel metal hydride cells. The bq2063
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
bq2063 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).
