Part Number: BQ24172 Hi team,
In datasheet, fast charge timer range is 1~10h. Customer met an issue that their battery is large and they need fast charge time longer, like 12~13h. Now customer connect 0.147uF capacitor to TCC. The question is that if…
Part Number: BQ24172 Hello,
I had select the BQ24172 IC charger , to charge 1S2P battery with a voltage 4.2V and Ichg =3A , I did all the calculation to determine the passive R,C and L, but i still don't know how to select Q1, Q2 and Q3 ( MOSFETs) as…
Part Number: BQ24172 Hi
My customer want to set different charging current when the system in different mode.
They want to charging 3 series battery with 4A when system in standby mode. And 0.8A charge the battery when the system in work mode.

Part Number: BQ24172 Hi,
Is there a battery discharge protection function on BQ24172? If not, which protection IC is recommended in this case?
Thank you.
Part Number: BQ24172 We are having very hard time passing EMI test (FCC) for the past 1 year. We followed all design/layout recommendations from datasheet and tips/advice from TI E2E forum regarding EMI improvements for BQ24172 IC. Also, we consulted…
Part Number: BQ24172 Hello, TI expert
It seems the battery reverse discharge to the adapter in our custom design. My question is whether the high side mosfet in BQ24172 is off when it is on sleep state.
And the schematic design showes above…
Part Number: BQ24172 Hi Team,
My customer is asking about if we have some method to detect battery absence after adapter removed. Since they need consider to add a supercap as the battery backup. I saw our battery detection is processing during charging…
