Tool/software:
Hi,
In te datasheet, I see about TSREF :
table 6-1 , page4 : Connect TSREF to the top of the thermistor resistor divider network to the GPIOs when they are configured for thermistor temperature monitoring. Bypass TSREF with a capacitor to AVSS
But the BQ79631EVM use the TSREF as a bias voltage for Differential voltage sense input.:
and to power supply a logic gate :
Following the datasheet of BQ79631-Q1, I think it's more normal to use CVDD to supply logic gate and AVDD to make a bias voltage , isn' it ?
in §7.5 Electrical Characteristics of the datasheet of BQ79631-Q1, I note that TSREF current limit is : min= 15mA/typ=30mA/max=52mA. What does it mean ? I I use it as a an output power supply, the current drawn from TSREF must be lower than the minimum =15mA ?
In the same way, If I plan to use AVDD and CVDD as power supplies, tha maximun current drawn must be lower tan the minimun ?
thanks,
Jerome
