We need 12V Li-ion/poly switching battery charger with power path management IC .Pls suggest any part no.
I assume 12V is the input source? What is the battery capacity and/or charging current?

In reply to Jeff F:
Also, do you have host I2C control or do you need resistor only configurable charger? Our newest family is the BQ25600 family. The B25606 is the non-I2C version.
Battery pack voltage -12V,Capacity -20000mAh,Charging current - >1.5A
In reply to saravanan krishnan1:
If you have a > 12V input source, I recommend the standalone BQ24610 controller with external FETs or BQ24171/2 with internal FETs. Both are standalone.
If your source could drop below 12V, then I recommend BQ25713 which requires host control through I2C.
Thanks. We have exactly 12V input source so BQ24610 is OK?
The BQ24610 is a buck only charger and needs some headroom (~0.5V) above the final battery regulation voltage for fast charging. If your input source is not higher than your battery then you must use a boosting or buck and boosting charger like BQ25713.
