Part Number: BQ25172 Other Parts Discussed in Thread: BQ2002 , Tool/software: Hi team,
This device does not have the function to detect ΔV and stop charging.
While devices like the BQ2002 have this function,
is there any reason why recent NiMH…
Part Number: BQ25172 Tool/software: Howdy! Want to make sure I understand the datasheet correctly,
I think grounding TS = standby. Shutdown = lowering VIN below ~2.8V. Difference between the two looks about 100uA IQ
im a bit confused by the IQ section…
Part Number: BQ25172 Tool/software: Hi all,
I would like to ask the question about Vout_ovp.
I think the pressure value of NiMH battery is usually 1.5~1.6V,
but the voltage value of this device to detect end of charge is 1.7V(typ), which is higher than…
Part Number: BQ25172EVM Tool/software: Hi,
I am experiencing an issue with the battery charger. At first, the charger worked well for about 15 charges. After that, it started detecting faults in the middle of charging and would stop. Now, it detects…
Part Number: BQ25172 Tool/software: Deat TI experts,
My customer considers BQ25172 for their new project. And they have few questions.
1. I saw that NiMH battery charger only use constant current mode for charging.
And termination condition is explaind…
Part Number: BQ25172 Tool/software: Hello Support Team,
I'm using a BQ25172EVM and 3 NiMh batteries in series.
I'm trying to configure the EVM to charge three cells as follows:
S1 : R2
S2 : R12
JP6 : Fixed
JP7 : Open (No jumper shorted)
JP4 …
Part Number: BQ25172 Hello e2e team,
I am currently working with the BQ25172 NiMH battery charger and have a question regarding the VSET pin detection for a 3-cell AAA NiMH battery configuration. According to the datasheet, the standard VSET resistor…
Part Number: BQ25172 Other Parts Discussed in Thread: BQ25170 Hello team,
Is there any FMEA document for this device?
If this device is in failure, is IN to OUT going to be SHORT or OPEN?
Best Regards, Kei Kuwahara
Part Number: BQ25172 I am using the BQ25172 in a stand alone base charger for a single cell (button) NimH powered plugin device from a 5V USB connection (regulated PS or PC)
I have ISET=27K / VSET=47K / TS=10K (not used) / TMR=24K connected as per the…
Part Number: BQ25172 (1) I'm trying to configure a Ni-MH charging circuit using BQ25172.
ISET=500mA@600ohm VSET=3cell+Inter,18kohm TS=Therm 10kohm VIN=5V-1A
In this case, VOUT_OVP=1.7V×3cell=5.1V, which exceeds VIN=5V. Is it possible to detect…
