The MAX17320 is a 38µA IQ stand-alone pack-side fuel gauge IC with protector, battery internal self-discharge detection, and optional SHA-256 authentication for 2 to 4 series lithium-ion/polymer batteries.The IC monitors the voltage, current, temperature and state of the battery to provide protection against over/undervoltage, overcurrent, short-circuit, over/undertemperature, overcharge, and internal self-discharge conditions using external high-side N-FETs, and provides charging prescription to ensure that the battery operates under safe conditions, thereby prolonging the life of the battery. The IC balances the cells using internal FETs. During prequal charging, the IC uses the CHGFET to linearly control charging.To prevent battery pack cloning, the IC integrates SHA-256 authentication with a 160-bit secret key. Each IC incorporates a unique 64-bit ID.The fuel gauge uses Maxim ModelGauge™ m5 algorithm that combines the short-term accuracy and linearity of a coulomb counter with the long-term stability of a voltage-based fuel gauge to provide industry-leading fuel gauge accuracy. The IC automatically compensates for cell aging, temperature, and discharge rate, and provides accurate state-of-charge (SOC) in milliampere-hours (mAh) or percentage (%) over a wide range of operating conditions.The IC provides a configurable always-on LDO that can power small critical loads on the system side without overloading the cells even under fault conditions. Dynamic power functionality provides the instantaneous maximum battery output power which can be delivered to the system without violating the minimum system input voltage.A Maxim 1-Wire® or 2-wire I2C/SMBus interface provides access to data and control registers. The IC is available in a lead-free, 2.4mm x 2.6mm 30-bump 0.4mm pitch WLP and 4mm x 4mm 24-pin TQFN packages.ApplicationsDigital Still, Video, and Action CamerasHandheld Computers, Radios, and TerminalsMedical Devices, Health and Fitness MonitorsPower Tools, Wireless Speakers, and DronesSmart Batteries and Battery BackupSmartphones, Tablets, and 2-in-1 Laptops

The MAX77757 is a standalone 3.15A charger with integrated USB Type-C®CC detection with JEITA compliance that supports reverse boost capability. The fast-charge current is easily configured with resistors. The MAX77757 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 MAX77757 enable automatic USB Type-C power source detection and input current limit configuration. To support a variety of legacy USB types as well as proprietary adapters, the IC also integrates BC1.2 detection using the D+ and D- pins. The IC runs the CC pin and BC1.2 detection automatically as soon as a USB plug is inserted without any software control.The IC also offers reverse-boost capability up to 5.1V and 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 THM pin low.The MAX77757 is equipped with a Smart Power Selector™ and a battery true-disconnect FET to control the charging and discharging of the battery or to isolate the battery in case of a fault. The MAX77757 is offered in several variants to support Li-ion batteries with various termination voltages from 4.1V to 4.5V. It also has a 3.6V termination voltage option for LiFePO4 batteries. 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 MAX77960B/MAX77961B are high-performance wide-input 3A (MAX77960B)/6A (MAX77961B) buck-boost chargers with Smart Power Selector™ and operate as a reverse buck converter without an additional inductor, allowing the ICs to power USB on-the-go (OTG) accessories. The devices integrate low-loss power switches and provide high efficiency, low heat, and fast battery charging in a small solution size. The reverse buck has true load disconnect and is protected by an adjustable output current limit. The devices are highly flexible and programmable through I2C configuration or autonomously through resistor configuration.The battery charger includes the Smart Power Selector to accommodate a wide range of battery sizes and system loads. The Smart Power Selector allows the system to start up smoothly when an input source is available even when the battery is deeply discharged (dead battery) or missing. For battery safety/authentication reasons, the ICs can be configured to keep charging disabled, and allow the DC-DC to switch and regulate the SYS voltage. The system processor can later enable charging using I2C commands as appropriate. Alternatively, the ICs can be configured to automatically start charging.ApplicationsUSB Type-C Powered Wide-Input Charging Applications2- and 3-Cell Battery-Powered DevicesSmartphones, Tablets, and 2-in-1 LaptopsMedical Devices, Health and Fitness MonitorsDigital Still, Video, and Action CamerasHandheld Computers and TerminalsHandheld RadiosPower ToolsDronesBattery BackupWireless Speakers
