Hello,
Could you please review my customer design? He says CHG does not disable when Vhot<1.4V (Vdrv * 0.3).
He connects LED to /CHG pin to check that.
<Parts used>
THermistor
0℃：Rcold＝27.22kΩ／60℃：Rhot＝3.01 kΩ
<Designed value>
RLO：13kΩ ／ RHI：5.9 kΩ
<Test procedure>
Heating thermistor with a hair dryer, and then observe the TS pin.
Heat until TS pin voltage goes below Vhot = 1.4V.
When charging stopped, /CHG LED is supposed to turn off.
Please feel free to correct me if I'm wrong. Thank you.
Regards,
Itoh
