Introduction

AI Translation

IP5209T is a multi-function power management SOC integrating a boost converter, lithium battery charge management, and battery level indication, providing a complete power solution for power banks.

The high integration and rich feature set of the IP5209T require minimal external components in application, effectively reducing overall solution size and lowering BOM cost.

The IP5209T requires only a single inductor to implement both buck and boost functions. The DC-DC converter operates at 500KHz, supporting low-cost inductors and capacitors.

The IP5209T synchronous boost system delivers 2.4A output current with conversion efficiency up to 95%. Under no-load conditions, it automatically enters sleep mode, reducing quiescent current to 50uA.

The IP5209T adopts switched charging technology, delivering 2.1A current with charging efficiency up to 96%. Built-in IC temperature and input voltage intelligently regulate charging current.

The IP5209T supports customizable battery level curves for accurate battery level display. Supports 4, 3, 2, and 1 LED battery level indication and lighting functions.
