Description
The BQ24070RHLR is a high-performance, integrated battery management IC specifically designed for single-cell Li-Ion and Li-Polymer battery applications. It features Dynamic Power-Path Management (DPPM), which intelligently manages the power distribution between the external input source and the system load. This ensures that the system can operate and boot up even when the battery is completely depleted, as the input source is prioritized for the system load while simultaneously charging the battery.
By integrating both the charger and power-path control into a compact VQFN-20 package, the BQ24070 reduces the overall component count and PCB space required for your design. It is an ideal solution for portable devices that require a seamless, reliable power supply transition between battery and external power.
Key Features
- Dynamic Power-Path Management (DPPM): Automatically optimizes the power split between the battery and the system load to ensure stable operation.
- System-First Power: Allows the system to power up immediately from an external input, regardless of the battery’s current charge state.
- Integrated Charging: Manages the complete charging cycle (pre-conditioning, constant current, and constant voltage) for single-cell Li-Ion batteries.
- Compact VQFN-20 Package: Offers a small footprint with excellent thermal characteristics, perfect for space-constrained mobile electronics.
- Robust Safety Features: Includes thermal regulation, over-voltage protection, and charge monitoring to keep your battery and device protected at all times.
Application
- Portable Consumer Devices: Ideal for smartphones, e-readers, and handheld gaming consoles that require efficient power management.
- Wearable Electronics: Its small size and efficient power path make it a great choice for smartwatches and health trackers.
- Industrial Handhelds: Provides reliable power switching for equipment that must remain operational even while charging in the field.
- Medical Gadgets: Ensures critical devices can maintain operation while managing battery charging cycles safely.
- DIY Embedded Projects: An excellent, professional-grade component for hobbyists and developers building sophisticated, battery-powered electronic prototypes.
