BQ24070RHLR Typical application Circuitry

BQ24070RHLR

The BQ24070RHLR is a highly integrated lithium-ion or lithium-polymer battery charge management IC designed for a wide range of portable applications. This chip features integrated power FETs and current sensor, high-accuracy voltage and current regulation, and charge status indication, making it a versatile solution for efficient battery management.

Application Scenarios

The BQ24070RHLR is perfectly suited for portable devices that require efficient, safe, and reliable battery charging, such as smartphones, portable speakers, handheld gaming devices, and other personal electronics that utilize single-cell lithium-ion or lithium-polymer batteries.

Parameter Features

- Programmable Charge Current: Supports adjustable charging current up to 2A, allowing for fast charging of the battery.

- Wide Input Voltage Range: Operates with input voltages from 4.35V to 16V, compatible with USB sources and higher voltage adapters.

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

- Charge Status Outputs: Provides outputs for LED or other indicators to display charge status and fault conditions.

Circuit Connection Example: Smartphone Battery Charging

In this scenario, we will design a battery charging circuit for a smartphone using the BQ24070RHLR.

1.Power Supply Connection:

- VIN Pin (Pin 10): Connect this pin to the positive terminal of your external power source, such as a USB charger or wall adapter.

2.Battery Connection:

- BAT Pin (Pin 7): This pin connects directly to the positive terminal of the lithium-ion or lithium-polymer battery that you're charging.

3.System Load Connection:

- SYS Pin (Pin 6): This pin provides power to the system load. It can be connected to the system power rail of the smartphone, ensuring the device operates smoothly during charging.

4.Charge Management and Tracking:

- ISET Pin (Pin 4): To adjust the charging current, place a resistor between this pin and ground. The resistor's value dictates how much current is used to charge the battery.

- TS Pin (Pin 8): This pin can be connected to a temperature sensor placed near or on the battery. It's used for temperature monitoring during the charging process to ensure safety.

Design Considerations:

- Power Source Compatibility: Verify that the power supply is able to provide enough voltage and current to meet the BQ24070RHLR specifications for the best possible charging.

- Thermal Management: Given the potential for significant power dissipation, especially at higher charging currents, implementing proper thermal management on the PCB is crucial.

- Battery Protection: While the BQ24070RHLR includes multiple safety features, additional protection mechanisms such as overvoltage, undervoltage, and short-circuit protection at the system level might be necessary to safeguard the battery and device.

Incorporating the BQ24070RHLR into a smartphone's power management system provides an efficient, compact, and safe solution for charging lithium-ion or lithium-polymer batteries, enhancing the device's usability and user experience.
