Overview
The TPB4056A20-DFGR is a single-cell lithium-ion battery charging management IC manufactured by 3PEAK. It supports USB Type-C input and provides constant current/constant voltage (CC/CV) charging profiles for 3.7V lithium batteries. The device integrates power path management, allowing system operation during charging. Key electrical specifications include an input voltage range of 4.35V to 5.5V, a fixed charging termination voltage of 4.2V, and a programmable charge current via an external resistor. It operates within a temperature range of -40°C to +85°C and is housed in a DFN2X2-8 package.
Feature Summary
- Integrates CC/CV charging algorithm with power path management for seamless system transition
- Supports USB Type-C interface input for versatile connectivity
- Includes comprehensive protection features against over-voltage, over-current, and thermal anomalies
Applications
- Single-cell 3.7V lithium battery charging modules
- Portable electronic devices requiring USB-C power input
- Battery-powered embedded systems with power path requirements
Procurement Notes
Verify the specific suffix DFGR corresponds to the required tape-and-reel packaging configuration. Confirm that the internal charge current setting aligns with your design's external resistor selection, as the base part number may not define the exact current limit without the resistor value. Ensure the supplier source is authorized to guarantee component authenticity and traceability for safety-critical battery applications.
Selection Notes
Select this component when designing a compact, single-cell lithium battery charger with USB-C input. It is suitable for applications requiring integrated power path management to allow system operation while charging. Consider the DFN2X2-8 package size constraints and the need for an external programming resistor to set the desired charge current level.
Part Context
This component belongs to the TPB4056A series of battery chargers from 3PEAK. It is designed specifically for single-cell lithium-ion or lithium-polymer batteries. The series focuses on providing a complete charging solution in a minimal footprint, integrating both the charging controller and power path management functions to simplify PCB layout and reduce component count in portable designs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility and electrical parameter alignment if considering alternative manufacturers' single-cell USB-C chargers.
