Hi Ali
We do have a buck-boost charger, but it is overkill for 1 cell at 100mA.
A possible alternative is to use a two IC solution. We have a buck-boost power supply family TPS630XX that could power the battery charger BQ25170.
Take a look at the TPS63020…
Part Number: BQ25170 Tool/software: Hello I have designed the attached schematic using the BQ25170 for a battery charging circuit intended to be used with a LR2032 battery.
I would appreciate any feedback!
Features: 4.2V charge voltage
10mA charge current…
Part Number: BQ25170 Tool/software: Hi team,
In case that TS pins is used as Charge Enable, Both enable and disable threshold voltage are low value. Is there any way to make the threshold around 0.8V?
Best regards, Goto
Hi Pragash
The BQ25170 has a 10 hour safety timer. If charge does not complete the unit will turn off. If unit is in thermal regulation with reduce output current the timer is doubled, max 20 hour. Charge needs to complete in 20 hours or less.
Check the…

I want to connect battery-level monitoring from my battery charger output. I have sent private messages on the circuit and connection. Please look at it and advise when you have time. Thanks.
Part Number: BQ25170 Tool/software: I am looking for a solution to charge a 3V coin cell battery (rechargeable) (Panasonic ML-2020) that will be used as battery back for a RTCC. Is the BQ25170 the right solution, or can you recommend the correct IC? …
Part Number: BQ25170 Tool/software: Hi,
Does TI have solution similar to the MCP73837?
Customer charger SPEC:
1cell Li-Ion: 4.2V . Charge current: 15mA
Thanks & best regards,
Part Number: BQ25170 Tool/software: Hi,
I designed a charger with a digital potentiometer connected to the VSET pin. The datasheet provides a table with discrete resistance and end charge voltage values.
The voltage variation with the resistance is…
