1 / 37 page  MP2632 All-in-One, 3A Battery Charger with 3A Boost Current MP2632 Rev.1.0 www.MonolithicPower.com 1 6/24/2016 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2016 MPS. All Rights Reserved. DESCRIPTION The MP2632 is a highly integrated, flexible, switch-mode battery charger with system power- path management and is designed for single-cell Li-ion or Li-polymer battery use in a wide range of applications. The IC can operate in both charge mode and boost mode to allow for full system and battery power management. The IC has an integrated IN-to-SYS pass-through path to pass the input voltage to the system. The pass-through path has built-in over-voltage and over-current protection and has a higher priority over the charging path. When the input power is present, the device operates in charge mode. The MP2632 detects the battery voltage automatically and charges the battery in three phases: trickle current, constant current and constant voltage. Other features include charge termination and auto-recharge. The MP2632 also integrates both input current limit and input voltage regulation to manage input power and meet the priority of the system power demand. In the absence of an input source, the IC switches to boost mode through PB to power SYS from the battery. In boost mode, OLIM programs the output current limit, and the IC turns off at light load automatically. The IC also uses output short-circuit protection to disconnect the battery from the load completely in the event of a short-circuit fault. The MP2632 resumes normal operation once the short-circuit fault is removed. The 4-LED driver is integrated for voltage-based fuel gauge indication. Together with torch-light control, the MP2632 provides an all-in-one solution for power banks and similar applications without an external micro-controller. The MP2632 is available in a 26-pin QFN (4mmx4mm) package.
