Product Descriptions

IP5209 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.

IP5209’s high integration and rich features make the minimized component number in application. It can effectively downsize the application and lower the BOM cost.

IP5209 only needs a single inductor to realize step-down and step-up.

IP5209’s synchronous step-up converter provides max 2.4A output current. Its efficiency is up to 96 PERCENT. It can switch to standby mode at empty load automatically.

IP5209’s synchronous switching charger provides max2.1A charging current. Its efficiency is up to 97 PERCENT. It regulates the charging current by IC temperature and input voltage.

The built-in 14bit ADC in IP5209 measures battery voltage and current accurately. ADC data are available on I2C interface. IP5209 has integrated a fuel gauge algorithm, acquiring battery’s state of charge precisely.

IP5209 can customize battery’s SOC curve, and indicate the SOC accurately, with the SOC indicator of 3/4/5 LEDs and flashlight function.

IP5209 is available in QFN24.
