Hello,
I am using LM3658SDX to charge LI-Ion battery 500mAh. I am really puzzled with the charging profile. I am using CH_IN (the rating on the supply is 5V output 500mA) and Rset is 5.6K (I am charging at 2500/5.6K = 446mA). I am monitoring the battery…

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…
If this IC is planned to be used at high temp charging say around 50C, how can JEITA standard be incorporated into circuit? Do we need to add discrete components to limit charging profile as per JEITA?
Other Parts Discussed in Thread: LM3658 Hello.
We are interested in a battery charger. Something like LM3658, but we need to set the USB current to any level we want. This part allows only 100mA/500mA with a logic level at one of its pins. Could you recommend…
Hello,
I am new to TI. It is my very first thread on this forum. So it would be helpful if someone answers my question. I am using LM3658-A for my project, but I want to use only. So what is best option for rest of pins which are unused i.e.CHG_IN, STAT1…
Other Parts Discussed in Thread: LM3658 Hi all,
I'm using LM3658 as my project battery charging solution. I'm using Li-ion Battery with 2050mAh, with embedded protection circuit which i got it from farnell

Other Parts Discussed in Thread: LM3658 Hi all,
LM3658 Icc_stby current is specified typically at 400[uA] with max 600[uA].
But who could give me the minimum specification (I want to measure this current)?
I have in my hand a chip that has a Icc of 25[uA…
Other Parts Discussed in Thread: LM3658 Hello!
Is the LM3658 Li Battery charger protected against a cell being connected backwards?
Any feedback or input is welcomed and appreciated!
Thanks again!

Other Parts Discussed in Thread: LM3658 Hi,
I wanted to inquire if the LM3658 is recommended for new designs and if there is some plan to discontinue it.
The reason I am asking is because one of our customers is interested in it for a new design that…
Hello Anis,
The fact that you are seeing only 110mA from the USB port suggests that what ever device you are pulling power from is only a USB 1.0 port or a port configured as a Standard Downstream Port (SDP) at only 100mA.
The LM3658 is attempting to…
