Description	1-Cell Li+ Charger
Datasheet	MAX1874_MaximIntegratedProducts.pdf

The MAX1874 charges a single-cell Li+ battery from both USB and AC adapter sources.

include a CHG output to indicate when battery current tapers below a predetermined level. DC power-OK (DCOK), USB power-OK (UOK), and poweron (PON) outputs indicate when valid power is present. These outputs drive logic or power-selection MOSFETs to disconnect the charging sources from the load and to protect the MAX1874 from overvoltage. The MAX1874 contains no logic for communication with the USB host. It must receive instructions from a local microcontroller. The MAX1874 is available in a 16-.
