Part Number: BQ25611DEVM
Other Parts Discussed in Thread: BQ25611D,

Hi,

for part number BQ25611D, TS pin is used for Battery NTC thermistor temperature sense in datasheet

but in BQ25611DEVM, development board design TS pin is not connected with Middle pin of battery connector - ideally middle pin of battery connector J4 used for NTC connection, but in dev board design middle pin of battery connector J4 is connected with BTSNS pin ! looks strange. Can you pls confirm in dev board design TS pin is connected with resistor divider network but not connected with battery connector ?

Regards,

Hi, the reason TS pin is connected to one of battery pack pins is that usually NTC thermistor is packed with battery pack connected to one of battery pack pinout. If a battery without hermistor packed in, TS pin could be connected to the thermistor instead. If TS pin is not used, connected a 10k resistor from REGN to TS and 10k resistor from TS to GND.

Regards,

Hong
