Part Number: BQ24088 Hello,
We've recently designed the BQ24088DRCR charger in one of our products but it seems like the Charge Termination phase is never entered. When Vin is set to 5V, I in is 0.5A (as expected). But as the LiPo is approaching 4.2V…
Part Number: BQ24088 Other Parts Discussed in Thread: BQ25100 Hi everyone!
I'm working on a design using the BQ24088 to charge an internal LiPo battery. We want to implement a simple battery charge percentage tracking algorithm based on the battery's…
Part Number: BQ24088 Hi,
We are designing a 1cell Li-ion custom battery pack.
The issue is that in order to fulfill one certification the design must pass, the battery pack shall have a set of diodes in the charge path connector and the Voltage Bat monitoring…
Other Parts Discussed in Thread: BQ24088 Hello,
I'm using four bq24088 in a charger for four batteries, but i'm experiencing a strange behavior: i place a battery in position 1 and i get a green LED (stat2), however when i put the same battery in any…

When using a single module the stat2 pin stays low for approximately 1-2 seconds after I remove the battery.
If I parallel 4 units (common input supply) the stat2 pins on all stay low for at least a minute after battery removal.
Why would this happen?

Thank you for the comments. You are right, that the high input voltage limits the selection. We have decided to have a 5V regulator in front of the charger and then many more devices shows up. We might also go for 4.2V charging as the Panasonic cells…

We have a rechargeable application using an MSP430F2274. Li-ion battery recharged from a TI bq24088 charge management IC. The battery feeds a TI TPS79930 LDO.
Most of hundreds…
