PURPOSE
The ManufactureDate() provides the system with information that can be used to uniquely identify a
particular battery pack when used with SerialNumber().
SMBus PROTOCOL ReadWord
OUTPUT
Unsigned integer—packed date of manufacture.
FIELD
Day
Month
Year
BITS USED
0...4
5...8
9...15
FORMAT
5-bit binary value
4-bit binary value
7-bit binary value
ALLOWABLE VALUES
0–31 (corresponds to date)
1–12 (corresponds to month number)
0–127 (corresponds to year biased by 1980)
SerialNumber() (0x1c); [0x1c]
DESCRIPTION
This function is used to return a serial number. This number, when combined with the
ManufacturerName(), the DeviceName(), and the ManufactureDate(), uniquely identifies the battery
(unsigned int). The bq2060 sets SerialNumber() to the value programmed in Serial Number EE
0x18–0x19.
PURPOSE
The SerialNumber() function can be used to identify a particular battery. This may be important in
systems that are powered by multiple batteries where the system can log information about each
battery that it encounters.

OUTPUT Unsigned integer
ManufacturerName() (0x20); [0x20-0x25]
DESCRIPTION
This function returns a character array containing the battery’s manufacturer’s name. For example,
MyBattCo would identify the Smart Battery’s manufacturer as MyBattCo. The bq2060 sets
ManufacturerName() to the value programmed in Manufacturer Name EE 0x20–0x2a.
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,
DeviceName() of BQ2060 would indicate that the battery is a model BQ2060. The bq2060 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).
