DS2437
ADB = A/D Converter Busy Flag. 1 = A/D conversion in progress on battery voltage; 0 = conversion
complete, or no measurement being made. An A/D conversion takes approximately 10 ms.
X = Don’t care
Bytes 1 and 2 of page 0 contain the last completed temperature conversion in the format described in the
“Operation - Measuring Temperature” section. Bytes 3-4 contain the last completed voltage A/D
conversion result and Bytes 5-6 contain the instantaneous current data. Refer to the appropriate section
for the data format of these locations. Byte 7 is reserved and will read out as all 1’s.
Page 1 (01h)
The second page, Page 1, contains the ICA and real time clock data. Both the RTC and ICA are volatile
read/ write locations so that they may be set, changed, or cleared by the host software. Bytes 0-3 contain
the RTC data, formatted as described in the “Operation - Real Time Clock” section. Byte 4 contains the
8-bit ICA. Bytes 5-7 are reserved and will read out as all 1’s.
Page 2 (02h)
The third page of memory (Page 2) contains the DISCONNECT TIME (first four bytes) and END OF
CHARGE (remaining four bytes) timestamps. This page is volatile and read / write. Refer to the
“Operation - Real Time Clock” section for the formatting of these locations.
Pages 3-7 (03h - 07h)
The remainder of the memory in the DS2437 (Pages 3 through 7) is backed with EEPROM. This memory
provides 40 bytes of user memory which may be used to carry any information the user wishes to store.
Additionally, the CCA/DCA information is stored in bytes 4-7 of page 7 if the DS2437 is configured
appropriately. If the CCA/DCA is used, page 7 should not be written to or current accumulator data will
be overwritten. See “Operation - Current Accumulators” for details.
