BQ24105RHLR Typical application Circuitry

BQ24105RHLR

The BQ24105RHLR is a sophisticated synchronous switch-mode battery charge controller designed to efficiently manage the power for single-cell Li-Ion or Li-Polymer batteries. It incorporates a wide range of features to optimize battery charging, making it suitable for portable applications where efficient charging and compact solution size are critical.

Application Scenarios

The BQ24105RHLR is ideal for various portable devices such as smartphones, tablets, digital cameras, and other small electronics that require efficient and controlled charging of their lithium-ion/polymer batteries.

Parameter Features

- Input Voltage Range: To accommodate a wide range of power sources, the BQ24105RHLR offers a wide input voltage range.

- Charge Current: It can provide a high charge current, which is adjustable through external components, allowing for fast charging of the battery.

- Integrated Power FETs: Contains internal power FETs for the charging and discharging paths, minimizing external component count.

- Charge Termination and Protection: Includes features like automatic recharge, pre-conditioning of deeply discharged batteries, and thermal shutdown for safety.

Circuit Connection Example: Charging Circuit for a Digital Camera

For a practical example, let's design a battery charging circuit for a digital camera using the BQ24105RHLR.

1.Power Input Connection:

- VIN Pin (Pin 1): This pin connects to the positive terminal of your external power source, such as a USB port or wall adapter.

2.Battery Connection:

- BAT Pin (Pin 5): Connect this pin to the positive terminal of the Li-Ion battery. The battery receives the charging current via this method.

3.Ground Link:

- Pins 2 and 4 (PGND and SGND): These pins need to be linked to the system ground. Proper grounding is crucial for the performance and stability of the charging process.

4.Charge Current Setting:

- ISET Pin (Pin 7): To adjust the charging current, connect a resistor between this pin and ground. The amount of the charging current can be adjusted to suit the needs of a certain battery by adjusting the value of this resistor.

5.Charge Status Indication:

- STAT Pin (Pin 6): This pin can be used to drive an LED or connect to a microcontroller for charge status indication, providing visual or programmable feedback on the charging process.

Design Considerations:

- Power Source Requirements: Ensure the power source can supply enough voltage and current as per the BQ24105RHLR specifications and the battery's charging needs.

- Thermal Management: Given the power dissipation during charging, especially at higher currents, implementing adequate thermal management practices is important. This could contain thermal pads or heat sinks, particularly in small or enclosed designs.

- Battery Compatibility: Verify that the chosen battery chemistry and specifications are compatible with the BQ24105RHLR's charging profile to ensure safe and efficient charging.

By integrating the BQ24105RHLR into a digital camera's power management system, designers can create a compact, efficient, and safe charging solution that enhances the device's usability and user experience. This setup ensures that
