battery charger

ali ekber gonca

I want to test your products like TPS61322DBZR, TPS61299XDRLR, TLV61046A, TPS61322DBZR, TPS61240DRVT . I will use these products with a battery charger integrated. The system I want to build will be as follows; I want to make a system like usb(5v)--> battery charger --->pil -->boost converter(5v). I aim that the system I will design in this way does not shut down and remains open all the time. Can you suggest me a battery charger and boost converter that I can work with?

We also know that Lipo batteries should not drop below 3.5V. The battery I will use will be a li-po battery, can you get back to me about it? I want a battery charger and boost converter that I can use in Li-po batteries.

Hi Ali,

To recommend a battery charger, can you provide more details below?

1. End equipment/application:

2. How many Lipo cells in series? Battery voltage range?

3. Charge current:

4. Control interface (standalone or host-controlled):

Thanks,

Chloe

Hi Chloe,

We will use a single cell li-po battery. As a charging current, 500mA will be enough for us.

In my application, there will be a card with products such as SIM module, nfc integrated.

My goal is to feed the card with usb and charge the battery with the charging integration from there.

I want the system not to shut down when I pull the usb, so I aim to supply it directly with the battery.
