BQ24800 - SMBus 1- to 4-Cell Buck Battery Charge Controller

The BQ24800 device is a high-efficiency, synchronous buck multi-chemistry battery charger supporting 1-, 2-, 3-, or 4-series Li+ cells, or other battery chemistries up to 19.2V. Through SMBus, a host microcontroller programs charge current, charge voltage, input current limit and discharge current.

BQ24800 Features

* Hybrid Power Boost Mode to power up system from adapter and battery together

* Ultra-fast transient response of 150µs to enter Hybrid Power Boost Mode

* Battery Only Boost Mode to support larger system transients and extend battery run time

* Peak power two-level in
