Product Descriptions

IP5189T is a fully-integrated multi-function power management SOC. It integrates a boost converter, a Li battery charger management system and a battery state of charge indicate controller. It provides a turn-key solution for power bank and portable charger applications.

IP5189T’s high integration and rich features make the minimized component number in application. It can effectively downsize the application and lower the BOM cost.

IP5189T only needs a single inductor to realize step-down and step-up.

IP5189T’s synchronous step-up converter provides 2.1A output current. Its efficiency is up to 92 PERCENT@VBAT=3.7V,Iout=2.1A. It can switch to standby mode at empty load automatically, the standby current reducing to 100uA.

IP5189T’s synchronous switching charger provides 2.1A charging current. Its efficiency is up to 91 PERCENT@ VIN=5.0V, VBAT=3.7V, Ibat=2A. It regulates the charging current by IC temperature and input voltage.

IP5189T integrates voltage based fuel gauge indication of 1/2/3/4 LEDs and flashlight function.

IP5189T is available in QFN24 (4*4mm).
