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

ADBMS2950 and ADBMS2952 are Battery Pack Monitors for electrical and hybrid vehicles, and other current or voltage sense applications. ADBMS2950 and ADBMS2952 measure the current flowing in and out of a battery pack by sensing the voltage drop over a shunt resistor with a very low offset.ADBMS2950 and ADBMS2952 also detect Overcurrent conditions using fast Overcurrent ADCs with digital threshold comparators and communicate their results through dedicated Overcurrent alert lines with minimum delay.ADBMS2950 and ADBMS2952 feature a total of 12 internally buffered high impedance inputs for measuring voltages from external sensors or resistor dividers, enabling measurement of pack voltages, temperatures, HV-Link voltages, chassis isolation, and the supervision of the state of contactors and fuses. Six digital outputs (GPO) supporting open-drain or push-pull can be used to control high voltage transistors to disconnect external resistor dividers. Four digital general-purpose inputs/outputs (GPIO) also allow operation as an I2C or SPI controller interface to address an external EEPROM or other serial peripherals.The built-in serial interface of ADBMS2950 can be configured for SPI or isolated isoSPI communication to the host. An additional isoSPI port allows to connect a daisy chain of ADBMS2950 devices; optionally extended with ADBMS6830 or ADBMS6832 (ADBMS683x) Cell Monitors. The ADBMS2952 supports SPI communication only.APPLICATIONS Electric and Hybrid Electric Vehicles Backup Battery Systems Grid Energy Storage
