IP2320 Ingenic Dual-Series Lithium Battery/Lithium-Ion Battery Charger Chip with 5V Input Power MOSFET

The IP2320 is a feature-rich charging management IC specifically designed for dual-series lithium batteries/lithium-ion batteries. Below is a detailed explanation of its features and applications:

Detailed Features:
1. 5V Input Synchronous Switching Boost Charging:
Allows the use of a 5V input source (such as a USB port) to charge dual-series lithium batteries/lithium-ion batteries.
Synchronous switching technology improves conversion efficiency.
2. Boost Charging Efficiency of 93%:
This is a very high efficiency, meaning minimal energy loss during the charging process.
3. Constant Voltage Charging Voltage Adjustable via External Resistor:
The full-charge voltage of the battery can be set using an external resistor to accommodate different types of lithium batteries.
4. Constant Current Charging Current Adjustable via External Resistor:
An external resistor can set the current during the constant current charging phase to protect the battery and optimize charging speed.
5. Automatic Input Current Adjustment, Adaptive to Adapter Load:
The IC can automatically adjust the input current to adapt to power sources provided by different adapters.
6. Supports Charging NTC Temperature Protection, Compatible with 10K NTC Resistor:
Uses an NTC (Negative Temperature Coefficient) resistor to monitor battery temperature, ensuring the battery does not overheat during charging.
7. Supports LED Charging Status Indication:
An LED light can be used to indicate charging status, such as charging in progress, fully charged, etc.
8. Built-in Power MOSFET:
The IC integrates a power MOSFET internally, simplifying circuit design and improving integration.
9. 400KHz Switching Frequency, Supports 2.2uH Inductor:
The high switching frequency allows the use of smaller inductors, further reducing circuit size and cost.
10. Output Overvoltage Protection:
When the output voltage exceeds the set value, the IC stops charging to protect the battery.
11. IC Overtemperature Protection:
If the IC's temperature becomes too high, it shuts down to prevent damage.
12. Input/Output Pins Withstand Voltage up to 20V:
The input and output pins can withstand voltages up to 20V, enhancing circuit robustness.
13. ESD Protection of 4KV:
The IC has 4KV electrostatic discharge protection, resisting electrostatic interference from the external environment.

Application Scenarios:
Mobile Devices: Such as smartphones, tablets, etc., which typically require high energy density and charging efficiency.
Power Tools: Some power tools that require higher voltage and current can use dual-series lithium batteries and charge them via the IP2320.
Drones/RC Models: These devices often use lithium batteries as a power source, and the IP2320 can help achieve safe and efficient charging.
Wearable Smart Devices: Such as smartwatches, health monitoring devices, etc., which require compact and efficient charging solutions.
In summary, the IP2320 charging management IC provides a powerful, efficient, and safe charging solution for dual-series lithium batteries/lithium-ion batteries.
