The ICs can operate as a reverse boost converter without an additional inductor, allowing the battery to share its power through the charging port, and offer programmable output voltage from 4.505V to 10.805V. The devices feature 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. The ICs feature true load disconnection in reverse boost mode and have an adjustable output current protection limit. The device is highly flexible and programmable through I2C configuration. Li-ion, Li-polymer, and LiFePO4battery chemistries are supported. It can also provide fast programmable unplug detection of sources for dynamic system load management. To support a variety of legacy USBs as well as proprietary adapters, the device also integrates BC1.2 detection using the D+ and D- pins.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 when 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.ApplicationsGaming DevicesVR ApplicationsmPOSTablet PCsSmart Power Selector is a trademark of Maxim Integrated Products, Inc.USB Type-C is a registered trademark of USB Implementers Forum, Inc.Power Path is a trademark of Linear Technology Corporation. |

MAX7778914VIN, 3AOUT 1-Cell Charger with Integrated USB Type-C Detection, DRP and OTG | Power Management (PMIC) | 1 | Active | The MAX77789 is a standalone, 3.15A charger with integrated USB Type-C®CC detection and reverse-boost capability. The IC operates with an input voltage of 4.6V to 13.4V 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 IC is operating in DRP (Dual Role Port) as a default and is capable of automatic USB Type-C power source detection and sink devices. To support a variety of legacy USB as well as proprietary adapters, the device 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 the USB plug is inserted without any software control.The IC offers reverse-boost capability up to 5.1V, 1.5A, which can be enabled with automatic way or register set by system MCU. The STAT1 pin indicates charging status, while the INOKB pin indicates valid input voltage. The EXTSM pin can be used to exit ship mode and force system to reset (POR), and STAT2 pin indicates fault detection and charger detection done indication by register bit selection.The IC 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 IC supports Li-ion and LiFePO4 batteries with various termination voltages from 3.6V to 4.55V. The IC comes in a 2.85mm x 2.85mm, 0.4mm pitch, 6 x 6 wafer-level package (WLP) making it suitable for low-cost PCB assembly.APPLICATIONSMobile Point-of-Sale (mPOS) TerminalsPortable Medical DevicesWireless HeadphonesGPS TrackersCharging Cradles for Wearable DevicesPower BanksMobile Routers |
