Milpitas, Calif –Linear Technology’s first devices in a new family of complete system-in-a-package µModule battery chargers support an output charge current up to 2A.
The LTM8061 features active input-current management to protect against supply rail droop, while providing maximum charge current to the load. The LTM8062 actively manages the output charge current to maximize the power sourced from a solar cell following Maximum Peak Power Tracking (MPPT) principles.The LTM8061 is specifically targeted for charging Li-Ion or Li-polymer batteries with float voltages of 4.1V, 4.2V, 8.2V and 8.4V. An externally adjustable float voltage allows the LTM8062 to support charging of single-and multi-cell Li-Ion, Li-polymer, Lithium iron phosphate (LiFePO4) and sealed lead acid (SLA) batteries up to 14.4V.
Key highlights:
- Complete 1MHz system-in-a-package step-down battery chargers in
9mm x 15mm x 4.32mm LGA package - 4.95V to 32VDC (40V Abs Max) operating input voltage range
- Adjustable charge current up to 2A (LTM8061)
- Precondition, constant-current, constant-voltage charging
- Internal minimum current or time-out charge termination
- Fixed 4.1V, 4.2V, 8.2V, 8.4V battery float voltage (LTM8061)
- Adjustable battery float voltage up to 14.4V (LTM8062)

This has good spec.The cost is on the highest side. A charger a basic cell phone with batteries are availble for about $25 the charger IC costs $9!

I would say this part is not targeted for simple cell phone charger. People can easily build a charge with BOM cost lower than $4 but this module idea can help reducing the board space and improve the reliability. I think that's the rationale behind such module approach.
