Other Parts Discussed in Thread: BQ2016 Hello everyone,
I have a few questions about the Bq2016 Fuel Gauge IC that hope someone may assist me on.
The first questions I have is about the sense resistor. I am using a 14.4 V NiMH rechargeable battery…
Other Parts Discussed in Thread: BQ2016 I am using the BQ2016 and having problems with the LMD register not updating properly.
On my prototype board (after a few hardware changes) my PFC starts out at 156 and LMD is 227 (after full power disconnection…
bq20z95 was designed specifically for Li-Ion. The chemistry IDs are also only available for Li Ion. It is possible that bq20z95 can be used for NiCd but it would be a lot of work to figure out the correct thresholds and chemistry values.
TI has other…
We do actually have a few NiCd/NiMH gauges, although they are quite long in the tooth due to the popularity of Lithium.
Try bq2013H, bq2014H, and bq2016. They are all single-wire communication.
We also have the bq2060A which offers multi-chemistry…
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…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
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…
