MAX1874, 1-Cell Li+ Charger

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

It also includes battery-to-input power switchover, so the system can be powered directly from the power source rather than from the battery.

In its simplest application, the MAX1874 needs no external MOSFET or diod

MAX1874 Features

* 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
