3 Description
IP5207T 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.
IP5207Ts high integration and rich features make
the minimized component number in application. It
can effectively downsize the application and lower the
BOM cost.
IP5207T only needs a single inductor to realize
step-down and step-up. Supporting of low-cost
capacitors and inductors.
IP5207Ts synchronous step-up converter
provides 1.2A output current. Its efficiency is up to
96%. It can switch to standby mode at empty load
automatically, the standby current reducing to 100uA.
IP5207Ts synchronous switching charger
provides 1.2A charging current. Its efficiency is up to
93%. It regulates the charging current by IC
temperature and input voltage.
IP5207T has integrated a fuel gauge algorithm,
acquiring batterys state of charge precisely.
IP5207T can customize batterys SOC curve, and
indicate the SOC accurately, with the SOC indicator of
4/3/2/1 LEDs and flashlight function.
IP5207T is available in QFN24.
