MAX8677AETG+
Analog Devices Inc.
The MAX8677A is an integrated 1-cell Li+ charger and Smart Power Selector™ with dual (DC and USB) power inputs. It can operate with either separate inputs for USB and AC adapter power*, or from a single input that accepts both. All power switches for charging and switching the load between battery and external power are included on-chip. No external MOSFETs are required.The MAX8677A features a Smart Power Selector to make the best use of limited USB or adapter power. The battery charge current and input current limit are independently set up to 1.5A and 2A, respectively. Input power not used by the system charges the battery. USB input current can be set to 100mA or 500mA. Automatic input selection switches the system load from battery to external power.Other features include overvoltage protection (OVP), charge status and fault outputs, power-OK monitors, charge timer, and battery thermistor monitor. Additionally, on-chip thermal limiting reduces the battery charge rate to prevent overheating. The MAX8677A is available in a 4mm x 4mm, 24-pin TQFN-EP package.ApplicationsDigital CamerasGPS NavigationPDAs, Palmtops, and Wireless HandheldsPortable Media/MP3 PlayersSmart Cell Phones

LTC3106IFE#TRPBF
Analog Devices Inc.
The LTC3106 is a highly integrated, ultralow voltage buck-boost DC/DC converter with automatic PowerPath management optimized for multisource, low power systems. At no load, the LTC3106 draws only 1.6μA while creating an output voltage up to 5V from either input source.If the primary power source is unavailable, the LTC3106 seamlessly switches to the backup power source. The LTC3106 is compatible with either rechargeable or primary cell batteries and can trickle charge a backup battery whenever there is an energy surplus available. Optional maximum power point control ensures power transfer is optimized between power source and load. The output voltage and backup voltage, VSTORE, are programmed digitally, reducing the required number of external components. Zero power Shelf Mode ensures that the backup battery will remain charged if left connected to the LTC3106 for an extended time.Additional features include an accurate turn-on voltage, a power good indicator for VOUT, a user selectable 100mA peak current limit setting for lower power applications, thermal shutdown as well as user selectable backup power and output voltages.Applications Wireless Sensor Networks Home or Office Building Automation Energy Harvesting Remote Sensors

MAX14745FEWX+T
Analog Devices Inc.
The MAX14745 is a battery-charge-management solution ideal for low-power wearable applications. The device includes a linear battery charger with a smart power selector and several power-optimized peripherals. The MAX14745 features two ultra-low quiescent current buck regulators and three ultra-low quiescent current low-dropout (LDO) linear regulators, providing up to five regulated voltages, each with an ultra-low quiescent current, allows designers to minimize power consumption and extend battery life in 24/7 operation devices, such as those in the wearable market.The battery charger features a smart power selector that allows operation on a dead battery when connected to a power source. To avoid overloading a power adapter, the input current to the smart power selector is limited based on an I2C register setting. If the charger power source is unable to supply the entire system load, the smart power control circuit supplements the system load with current from the battery. The charger also supports temperature dependent charge currents.The two synchronous, high-efficiency step-down buck regulators feature a variable frequency mode for increased efficiency during light-load operation. The output voltage of these regulators can be programmed through I2C with the default preconfigured. The buck regulators cansupport dynamic voltage scaling to further improve system power consumption.The three configurable LDOs each have a dedicated input pin. Each LDO regulator output voltage can be programmed through I2C with the default preconfigured. The linear regulators can also be configured to operate as power switches that may be used to disconnect the quiescent load of the system peripherals.The MAX14745 features a programmable power controller that allows the device to be configured for applications that require the device be in a true-off, or always-on, state. The controller also provides a delayed reset signal and voltage sequencing.The MAX14745 is available in a 36-bump, 0.4mm pitch, 2.72mm x 2.47mm wafer-level package (WLP).ApplicationsFitness MonitorsRechargeable IoT devicesWearable Electronics
