wow that sounds interesting. i wouldn't know how to implement that *gg*
looks like i need to read more literature on battery charging and chemistries :oops:

Re: Best charger for NiZn?

Does the USC distinguish between NiCd battery and NiZn battery automatically, or does the user have to tell the charger that the inserted battery is a NiZn chemistry?

Re: Eneloops: 2700 cycles and still going...

Thanks for the immense efforts with long-term Eneloops testing! Your test results confirm that the Japanese ones have extraordinary performance and one doesnt need to look elsewhere if in need for top quality NiMH cells.

For how many days did the test run? :P

Re: User guide for Mark's charger code

i'll agree,you're right with the esd diodes and clipping. however the absolute max rating in the specs is surpassed by your quoted 0.6v by 0.2v.
anyway i am right,ain't i,that the schematics don't have any explicit measure for rev pol protection?

Re: User guide for Mark's charger code

Hello Mark, the datasheet mentions that the absolute voltage, (or potential to GND), at the input pins should not become negative. With a 10k resistor in series the resulting current would be minimal but the pin voltage would imo still be negative, i am not sure though. I do know that the pins have ...

Re: User guide for Mark's charger code

I cannot discover any battery reverse polarity protection in the schematics. For example for BAT1_V, the signal (=absolute voltage, the potential with respect to GND) at the ADC pin would get negative if someone inserts a 1.2V battery in reverse direction, wouldn`t it :?:

Re: User guide for Mark's charger code

hey Mark, greetings from somewhere special i maybe getting some insight into internals ;)
Are you too into analyzing and critiquing schematics?
Well i am, but i am not the best at it :geek:

Re: User guide for Mark's charger code

Good to know, thank you Mark! I am now also wondering about the serial clocking frequency f(SCL) on the I²C bus line. That's given by the MCU ( master ), not the chip ( slave ), as far as i understood. From the installed pull-up resistors on the serial lines in Paul's schematics, it cannot be Highsp...

Re: User guide for Mark's charger code

Btw to which sampling rate is the ADC set (my guess: 3.75SPS or 3.75Hz for 18bits mode) and what kind of Conversion Mode (One-Shot or Continuous)? Thanks for some internal info on this :geek:

Re: User guide for Mark's charger code

Thanks Mark, i've read the interesting Ruggeduino article and learned a bit from it ;) Much of my knowledge originates from the BET site and i am beginning to understand more about resistors and Ohm's law. Thanks pfeerick, i am testing the contributions from the set of input protection measures as s...
