STC3100 Data sheet

[Yoshi441]

 

Hi all

My team are using STC3100 for our project. But just I confusing as following it

Please see as following URT

STC3100  data sheet mentioned Rev1.1 and Date of 19 Sep 2016

https://www.st.com/ja/power-management/stc3100.html#documentation

But this DL document is Rev1.0 and Data of 2009.

Where is data sheet Rev1.1(Date Sep 2016). Please let me know how to get it

Best Regards,

Dear Yoshi-san,

please let me confirm that the datasheet in rev 1.0 from January 2009 is the most recent version of the datasheet of STC3100, even though it is mentioned differently on the ST.com website. 

Best regards,
Benedikt

Hi Benedikt-san,

Just one question for STC3100

Page 3 : Mentioned that Vcc is 2.7 to 5.5V.

Page 4 : Electrical characteristics mentioned 2.7V < Vcc  < 4.5V

Do you know why Page 4 mentioned Vcc limited than page 3 (Vcc).

If you have some information for it, please let me know.

Best Regards,

Yoshi

Dear Yoshi-san,

 

You are right to point out that the voltage range between page 3 (operating conditions) and page 4 (electrical characteristics) is not identical. Please be assured that the gas gauge STC3100 is guaranteed to stay fully functional up to an operating supply voltage of 5.5V as specified on page 3. However, the circuit was designed to be most accurate in the voltage range of 2.7V < Vcc < 4.5V since the most common lithium-type batteries have a maximum charging voltage of around ~4.2V. Therefore the electrical characteristics are given in the range of 2.7V to 4.5V.

Best Regards,
Benedikt
