I've a few questions regarding this Charge Management controller IC.

On page 11, section 3.0, they have mentioned Charge Status Outputs (STAT1,STAT2), Timer Enable and on section 4.3, page 14, they have mentioned pre-conditioning.

I want to understand what is the meaning of pre-conditioning and its purpose with respect to this charge controller?

Also, what is the use of Stat1, stat2 and time enable pins? Like, what status information will I be getting with the 2 pins, it hasn't been mentioned in the datasheet.

And what's the purpose of timer and the Therm pin?
 

Hi,

I did a PDF search on "STAT1", "timer", "conditioning". Feel free to do the same.

Charge status:
* FIGURE 4-1, as well as
* TABLE 5-1 explains them.

Timer enable:
* read chapter 3.6
* and see FIGURE 4-1
* and so on.

Pre-conditioning:
First page says:
• Preconditioning of Deeply Depleted Cells
- Selectable Current Ratio
- Selectable Voltage Threshold
.. more informations availiable in the datsheet.

THERM:
* also is quite good explained on several locations.
additionally FIGURE 6-1 shows the schematic, and chapter 6.1.1.6 explains the function of RT1 and RT2.
***
So every single item is explained pretty good in the datasheet.
If you need more details, then please ask more detailed questions.

If you need support additional informations to the chip, please visit:
https://www.microchip.com/en-us/product/MCP73833
There - as usual - you can find additional documents (like application notes and user guides) as well as development boards.

If you want to understand rechargable batteries at all, then please visit www.batteryuniverity.com.
