The MAX77751 is a standalone, 3.15A charger with integrated USB Type-C® CC detection and reverse boost capability. The fast-charge current and top-off current thresholds are easily configured with resistors. The MAX77751 operates with an input voltage of 4.5V to 13.7V and has a maximum input current limit of 3A. The IC also implements the adaptive input current limit (AICL) function that regulates the input voltage by reducing input current, to prevent the voltage of a weak adapter from collapsing or folding back.The USB Type-C Configuration Channel (CC) detection pins on the MAX77751 enable automatic USB Type-C power source detection and input current limit configuration. To support a variety of legacy USB as well as proprietary adapters, the IC also integrates BC1.2 detection using the D+ and D- pins. The IC runs the CC detection and BC1.2 detection automatically without any software as soon as the USB plug is inserted.The IC also offers Reverse-Boost capability up to 5.1V, 1.5A, which can be enabled with the ENBST pin. The STAT pin indicates charging status, while the INOKB pin indicates valid input voltage. Charging can be stopped by pulling the ITOPOFF pin low.The MAX77751 is equipped with a Smart Power Selector™ and a battery true-disconnect FET to control the charging and discharging of the battery or isolate the battery in case of a fault. The MAX77751 is offered in several variants to support Li-ion batteries with various termination voltages from 4.1V to 4.5V. The IC comes in a 3mm x 3mm, 0.4mm pitch 24-lead FC2QFN package making it suitable for low-cost PCB assembly.ApplicationsMobile Point-of-Sale (mPOS) TerminalsPortable Medical DevicesWireless HeadphonesGPS TrackersCharging Cradles for Wearable DevicesPower BanksMobile Routers

The MAX77985/MAX77986 is a high-performance high input range 3.5/5.5A fast charger with Smart Power SelectorTM. The IC can operate as a reverse boost without an additional inductor, allowing the battery to share its power through the charging port with voltage programmable from 5V to 12V. The device features fully integrated low-loss power switches to provide a small solution size and high efficiency, even at high input voltage and high charging current. Its high switching frequency allows the use of a smaller sized inductor. Li-ion, Li-polymer, and LiFePO4 battery chemistries are supported. The IC is compatible with USB Power Delivery sources with input current capability up to 5A. It can also provide fast unplug detection of 9V and 15V sources for dynamic management of system load. The IC also helps mitigate EMI with the spread spectrum feature. The IC features true load disconnection in reverse boost mode and has an adjustable output current protection limit. The device is highly flexible and programmable through I2C configuration.The battery charger includes a Smart Power Selector to accommodate a wide range of battery sizes and system loads. The Smart Power Selector allows the system to start up gracefully as soon as an input source is available, even when the battery is deeply discharged (dead battery) or missing. It can be configured so that when power is applied to the charger input, the battery charging can automatically start. APPLICATIONS Gaming Devices VR Applications mPOS Tablet PCs

The MAX14920/MAX14921 battery measurement analog front-end devices accurately sample cell voltages and provide level shifting for primary/secondary battery packs up to 16 cells/+65V (max). The MAX14920 monitors up to 12 cells, while the MAX14921 monitors up to 16 cells. Both devices simultaneously sample all cell voltages, allowing accurate state-of-charge and source-resistance determination. All cell voltages are level shifted to ground reference with unity gain, simplifying external ADC data conversion.The devices have a low-noise, low-offset amplifier that buffers differential voltages of up to +5V, allowing monitoring of all common lithium-ion (Li+) cell technologies. The resulting cell voltage error is ±0.5mV.The devices’ high accuracy make them ideal for monitoring cell chemistries with very flat discharge curves, such as lithium-metal phosphate.Passive-cell balancing is supported by external FET drivers. Integrated diagnostics in the devices allow open-wire detection and undervoltage/overvoltage alarms. The devices are controlled by a daisy-chainable SPI interface.The MAX14920 is available in a 64-pin (10mm x 10mm) TQFP package with an exposed pad. The MAX14921 is available in an 80-pin (12mm x 12mm) TQFP package. Both devices are specified over the -40°C to +85°C extended temperature range.Applicationse-Transportation Energy PacksEnergy Storage PacksIndustrial Battery Backup SystemsTelecom Battery Backup Systems
