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: BQ34Z100-R2 Hi,
I have 3 Ni-MH battery cells connected in series to produce 3.6V. The charger in my design is BQ25172 (Ni-MH charger). Is there an IC that can check battery health and charge level and…
Part Number: BQ25172 Hi in-charge person.
Please let me know the BQ25172 OUT PIN rating with 1 cell charge setting.
In our development environment, BQ25172 OUT PIN may are input 2~3V voltage without Power supply.
We need to know the possibility of failure…
Part Number: BQ25172 Hi,
1. May I know BQ25172 can use in 2S2P application? Or anything need to noticed?
2. For IC temperature calculate, can I using (Vin-Vout) * Iout = Pd?
Thanks!
Jeff
This stat foot of BQ25172 says that it will flash when abnormality is detected. What does abnormality usually mean?Is there anything specific? Help to see why the stat foot of BQ25172 above will flash abnormally when no load is applied. According to the…
