IP5328P Boost Charging Bidirectional Fast Charging Mobile Power Module

IP5328P Boost Charging Bidirectional Fast Charging Mobile Power Module is a highly integrated, multi-protocol power management solution designed for building high-efficiency portable power banks. This versatile module incorporates both a boost converter for output and a switching charger for input, consequently supporting two-way fast charging. The IP5328P chip autonomously handles all major fast charging protocols, including PD3.0, QC3.0, AFC, and FCP, eliminating the need for external handshake circuits. Furthermore, its high level of integration minimizes external components, simplifying the design and lowering the total cost of materials. This module offers four power indicators, accurate voltage and current metering, and robust safety features, therefore making it the ideal choice for modern, high-capacity, quick-charge portable devices.

Key Features:

• Bidirectional Fast Charging: Supports fast charging input (module charging the battery) and fast charging output (battery charging the device).
• Multi-Protocol Support: Automatically supports major fast charge standards including QC2.0/3.0, FCP/AFC, SFCP, and PD2.0/3.0 (up to 18W).
• High Integration: Integrates the power management controller, power FETs, boost converter, and charging circuit, minimizing external BOM.
• Multiple Ports: Features integrated USB-A output ports, a Type-C port (bidirectional), and a Micro-USB port for flexible battery pack construction.
• Accurate Fuel Gauge: Provides highly accurate 4-LED status indication for battery capacity and charging/discharging status.

Pinout and Wiring:

• B+/B−: Connect the positive (B+) and negative (B−) terminals of the 3.7V Lithium battery pack here. Ensure correct polarity.
• K: Connect an external push button to the K pin and ground (GND) to activate the output (turn on the power bank).
• D+/D− Pads: These pads allow direct wiring to the data pins of the USB ports for custom configurations or quality testing.
• Wiring Note: Always use short, thick wires for the battery connections (B+/B−) to handle the high charging and discharging currents (up to 5A) efficiently and minimize voltage drop.
