Other Parts Discussed in Thread: BQ24167
I am using BQ24167RGET IC for battery charging (we are using 2300 and 4400 mAH capacity battery) , now BQ24167RGET is NRND and it Replaced By " BQ24166– The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device."
I refer Datasheet and find that ,
For the bq24166, two temperature thresholds are monitored; the cold battery threshold (TNTC < 0°C) and the hot
battery threshold (TNTC > 60°C). These temperatures correspond to the VCOLD and VHOT thresholds. Charging is
suspended and timers are suspended when VTS < VHOT or VTS > VCOLD.
For the bq24167 monitors four temperature thresholds; the cold battery threshold
(TNTC < 0°C), the cool battery threshold (0°C < TNTC < 10°C), the warm battery threshold (45°C < TNTC < 60°C)
and the hot battery threshold (TNTC > 60°C). These temperatures correspond to the VCOLD, VCOOL, VWARM, and
VHOT thresholds.
As with the bq24166, charging is suspended and timers are suspended when VTS < VHOT or VTS
> VCOLD. When VHOT < VTS < VWARM, the battery regulation voltage is reduced by 140mV from the programmed
regulation threshold. When VCOOL < VTS < VCOLD, the charging current is reduced to half of the programmed
charge current.
is there any other functionality change in bq24166 ?
if i use bq24166 in my design then is there any chance for degrade battery charging performance and battery life related issue ( like battery size increase. etc..)
i looking for your positive response ,
Thank you
