I am doing a PCB layout and cannot find the footprint for it. It is called is a 25DSBGA but there is also a reference in the datasheet called a WCSP-25 Pin. Does anybody know where I get get the footprint for a layout in Altium, it wasn't in the Texas…
If you have a microcontroller in your system, such as the MSP430, then this is usually done by simply looking at the D+/D- lines on the USB. Since you're using the same plug for both sources, the adaptor USB plug could be configured in hardware to short…
Other Parts Discussed in Thread: BQ24180 , BQ27510-G2 Hi,
We are considering using either BQ27510-G2 or BQ24180 with commercially available ipod nano batteries. Here is an example of one we are thinking.

TI recommends that you use TI charger parts, like the bq24180 and bq24160. If you have to use an LTC IC, I would suggest that you contact LTC for support.
Jeff, thank you for the tipps.
The numbers for registers correspond to the numbers of the BQ24180 registers R01, R02 etc, that could be modified from the software dialog. I hve discussed the issue with the customer and we found out, that the reasons…
Dilan,
The Ishort is small on bq24150A. But, bq24153/6/8 or bq24180 has a higher Ishort t rickle charge or precharge charging current.
Would you check the other IC?
Thanks,
Anthony,
What sort of application is this for? Our chargers are grouped by application type: linear, switchmode, host-controlled, stand-alone, etc. What is your input source? What charge rate do you want? Do you have a host (uC) in your system?

Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
