the R6 can be 1Mohm. the R1 and R2 is related to your requirement: at which input voltage, you need to indicated the low battery voltage. please refer the LBI/LBO principle description chapter of the datasheet for more detail
may i know why you want…
Hi Rajarshi,
I checked with my manager and we cannot recommend tying the two SYS pins together on any of our chargers with 1 shared battery or with 2 separate batteries. With 1 share battery, the issue is as follows. The SYS pin regulation has a wide…
Hi, I am looking for schematic and footprint libraries for some other but similar TI parts:
TPS63001
TPS61230
in Altium. If you have a full library with all TI power regulators that would be even more awesome as I generally use you regulators…
in the li-ion input voltage application, i would suggest TPS61230 instead of TPS61030. I guess the input current will not higher than 1A, so you can have a look at TPS61253 series or TPS61252.
thanks

Boost converters such as the TPS81256 and TPS61230 have 0% duty cycle mode where Vin is passed through to Vout when it goes above the setpoint. This might be ok for the application. If a regulated 5V is needed even when Vin is above Vout, a buck-boost…
There is a battery charger with an integrated boost charger, the BQ25570. I am not sure if the boost is rated for the current you require.
I don't know of a higher current verion of the LM2621, but if you don't need to start up from as low a voltage…
Part Number: LM3481-Q1 Other Parts Discussed in Thread: LM3481 , TPS61230 , LM5017
Hi
I received the following question from my customer.
Short protection function is mentioned on the datasheet.
However, I think that the LM3481 can not protect…
Other Parts Discussed in Thread: TLV320AIC3110 , TLV320AIC3110EVM-U , TPS61230 , TPS73233-EP , TPS73218-EP Hi
i'm working with a tlv320aic3110 codec in a medical application. I'm trying to generate a 1khz tone like in datasheet page 7, "DAC Headphone…
Thanks Jeff for your quick answer !
I'll stick to BQ25895 and use TS3USB2211 as a switch.
Some final questions:
Using the TS3USB221A switch, do I need to take specific care for USB detection (BC1.2) to work properly?
You told: "the bq25895M…
Thanks...
I am going to use This IC for basically powering my microcontroller SST89E516RD2 and also GSM module SIM800. SIM 800 consumes around 2Amp of current..
but the source voltage i have is from li-Io or Li-po battery (3v to 4.2v) and current…
