The BQ25896RTWR is an integrated circuit (IC) component designed for multi-cell, Li-Ion and Li-Polymer battery charging applications. It offers various key features that make it a highly efficient and reliable solution for charging portable electronic devices. Let's dive into its overview and key features in detail:
1. High Integration:
- The BQ25896RTWR combines a synchronous PWM controller, integrated FETs, and a host of protection features, resulting in a highly integrated charging solution.
- This integration allows for a smaller PCB footprint and overall bill of materials (BOM) cost reduction.
2. Fast Charging:
- The IC supports charging up to 3 battery cells in series, making it suitable for a wide range of portable devices requiring fast charging capabilities.
- It supports Input Voltage Dynamic Power Management (DPM) to maximize adapter utilization and optimize charging current when a lower power adapter is used.
3. USB Type-C Compatible:
- The BQ25896RTWR supports USB Type-C specification with multiple Type-C implementations, including standard Type-C, Type-C DRP (Dual-Role Port), and Type-C with Power Delivery (PD).
- It can negotiate power contracts with the source and load devices to achieve optimum charging rates
