Other Parts Discussed in Thread: BQ25040 I have been using the bq25040 successfully with its default mode. I now need to be able to switch to the USB100 mode. However, in spite of giving the chip either two or four pulses on the EN/SET line, it still charges…
Other Parts Discussed in Thread: BQ25040 , BQ24040 Hello,
I'm planing to use bq25040 in my project but I want to use it as a standalone device without any host microcontroller. Is it possible in some way to automatically terminate charge of the battery…
Other Parts Discussed in Thread: LM3658 , BQ24075 , BQ24040 , BQ25040 Hello:
We are currently using the TI LM3658 device in a few designs. In the field, we have had a few boards damaged by end customer use. We believe that some customers are plugging 12V…
Other Parts Discussed in Thread: BQ24050 , BQ25040 Hi all,
I've been looking at an issue that came up where customers have been noticing very long charge times in a few instances. I've noticed now a couple times after looking further into this problem…
Are you looking for a single cell battery charger? We have several to pick from, including the bq25040, bq24040, bq24030. All of those are linear chargers. The bq24150 is a switchmode charger.
