MAX8677A 19-0722 Rev 1 1/07 1.5A Dual-Input USB/AC Adapter Charger and Smart Power Selector General Description Features The MAX8677A is an integrated 1-cell Li+ charger and Complete Charger and Smart Power Selector Smart Power Selector with dual (DC and USB) power No External MOSFETs Required inputs. It can operate with either separate inputs for USB and AC adapter power*, or from a single input that Common or Separate USB and Adapter Inputs accepts both. All power switches for charging and System Operates with Discharged or No Battery switching the load between battery and external power are included on-chip. No external MOSFETs are Automatic Adapter/USB/Battery Switchover required. Load Peaks Over Adapter Rating Are Supported The MAX8677A features a Smart Power Selector to by Battery make the best use of limited USB or adapter power. Input Overvoltage Protection to 16V The battery charge current and input current limit are independently set up to 1.5A and 2A, respectively. 40m System-to-Battery Switch Input power not used by the system charges the bat- Thermal Regulation Prevents Overheating tery. USB input current can be set to 100mA or 500mA. Automatic input selection switches the system load CHG, DOK, UOK, and FLT Indicators from battery to external power. 5.3V (typ) SYS Regulation Voltage Other features include overvoltage protection (OVP), charge status and fault outputs, power-OK monitors, Ordering Information charge timer, and battery thermistor monitor. Additionally, on-chip thermal limiting reduces the battery PIN- PKG charge rate to prevent overheating.
