WTD: copy of Benchmarq data CD

[Philip Pemberton]

Hi,
I'm trying to track down a few application notes that were on one of the
Benchmarq Microelectronics data CDs. Does anyone know where I could get a
copy of the CD, an ISO9660 (.ISO) image or a ZIP file containing the contents
of the CD?
From what I can tell, the files I'm after are:
BQ2014.PDF
BQ2010.PDF
2014DUAL.PDF
2010TUT.PDF
EV2014.PDF
EV2014.ZIP
BQ2114.PDF

Thanks,

Benchmarq data is available on the TI website.

http://focus.ti.com/docs/prod/folders/print/bq2014h.html

Document names seem unchanged.

That's great. I got a copy of the evkit software from the Wayback Machine

(web.archive.org) and hacked together an interface pod using the schematic in
the evkit datasheet.
Only problem is, I can't see from the evkit (EV2014x.pdf) and device
(Bq2014.pdf) datasheets how to calculate the "Average Vsr Current", which I
need to calculate an estimation of the time the battery is going to last (at
the average load).
The Evkit software (EV2014.EXE) seems to get fairly accurate readings (60mA
seems about right for the motor, and 1A is about right for the halogen lamp),
but I'll be damned if I can work out how it does it.
As usual, source code is included for the communication routines and the
communication test tool, but the ZIP from Wayback didn't include the source
code for EV2014.EXE.
Problem is, the comms test tool allows you to read and write chip registers,
but it doesn't do any calculations on them. EV2014 reads the chip regs and
gives an average current measurement, and all the other useful little things.

Has anyone managed to work out how Benchmarq got the chip to divulge the
voltage on the SR pin (aka Vsr), from which the current running through the
battery is derived?

Thanks.
