Description

General part information

MAX77787 Series

The MAX77787 is a standalone, 3.15A charger with integrated USB Type-C®CC detection and reverse-boost capability. The fast-charge current and termination voltage is easily configured with resistors. The IC operates with an input voltage of 4.5V 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 enable automatic USB Type-C power source detection and input current limit configuration without any software control as soon as the USB plug is inserted. The IC also integrates BC1.2 and proprietary adapter detection using the D+ and D- pins.The IC offers reverse-boost capability up to 5.1V, 1.5A, that can be enabled with the ENBST pin, also BYP reverse-boost that can be enabled with the ENBST and STBY pin combination. The STAT pin indicates charging status, while the INOKB pin indicates valid input voltage. Charging can be stopped by pulling the CHGENB pin low.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 batteries with JEITA compliance. It also has another option that supports LiFePO4batteries with non-JEITA compliance. The IC comes in a 2.758mm x 2.758mm, 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
