Hi Garrett
do you have any recommendation like LM3658? which only have BATT power rail?
customer side don't need the BQ24079 VSYS feature. because they already have another battery charger to support it.

As LM3658 is an old part, Do we have any new device can replace it ?
Customer do need below inductors :
1-power down, charging is suspended or interrupted

1. I read the data sheet, but I didn't understand LM3658SD/NOPB, LM3658SD-A/NOPB, LM3658SD-B/NOPB. Can you briefly describe the difference and how to apply it?
2. I designed the LM3658SD/NOPB, but the delivery time is longer. I can use LM3658SD-A…
Part Number: LM3658 Hello, I am trying to implement battery charging circuit using LM 3658 using USB. I have connected LM 3658 in a similar way as shown in the evaluation board schematic. I am experiencing fluctuating voltage at Stat-1 pin due to rapid…
Part Number: LM3658
Hello,
I have problems with the LM3658 Charger IC. I use a Lithium Ion cell (nominal voltage around: 3,8V). I assembled the PCB with R26 = 2,7k.
Instead of 3.3V I used 5V as LED voltage.
After C19 my battery is plugged in.
Is there…
Other Parts Discussed in Thread: LM3658 We're using LM3658 to charge a Li-Po battery, using a USB.
USB_SEL is pulled high, so according to page 4 of the spec the charge current should range from 400mA to 500mA.
However, when we measure the actual charge…
Part Number: LM3658 We are using NP50 type batteries where we have set the charge current to be around 150mA. When most batteries are connected the initial charge current is around 50mA but sometimes it is around 360mA. When this occurs the LM3658 will…
I understand that after the battery reaches its destination voltage (4200mV in my case), this charger IC stops charging and will only resume when battery voltage drops 200mV below destination.
This period is referred to in the manual as "Maintenance Mode…
