BQ24314DSGR Typical application Circuitry

BQ24314DSGR

The BQ24314DSGR is an integrated circuit designed for charger port protection. It is specifically engineered to protect against overvoltage, overcurrent, and overtemperature conditions that might arise at the power input of portable devices. This makes it an ideal choice for applications in smartphones, laptops, tablets, and other portable electronics that are frequently charged through USB or other charging ports.

Application Scenarios

The BQ24314DSGR is particularly useful in devices that require protection against faulty chargers or cables, ensuring that the device remains safe even when exposed to potentially damaging charging conditions. It's a critical component in any portable device that prioritizes battery and circuit safety during the charging process.

Parameter Features

- Overvoltage Protection: The BQ24314DSGR can detect and respond to overvoltage conditions, protecting the device from receiving too much voltage.

- Overcurrent Protection: This safeguards against damage resulting from an increased current flow.

- Thermal Shutdown: The inclusion of a thermal shutdown feature enhances safety by turning off the device if it gets too hot.

- Broad Operational Voltage Range: This integrated circuit is suitable with a variety of power sources and chargers since it can withstand a broad range of operating voltages.

Circuit Connection Example: USB Charging Protection for a Smartphone

For a practical application, consider the integration of the BQ24314DSGR into a smartphone charging circuit to provide comprehensive protection against overvoltage, overcurrent, and overtemperature conditions.

1.Input Connection:

- VIN Pin (Pin 1): Connect this pin to the VBUS of the USB charging port. This pin will receive the input voltage from the charger.

2.Output Connection:

- VOUT Pin (Pin 5): The smartphone's charging circuitry should be linked to this pin. It delivers the protected voltage to the device.

3..Ground Connection:

- Pin 4, also known as the GND Pin, should be connected to the system ground. It acts as the operational reference point for the IC.

4.Allow and Status Signal:

- EN Pin (Pin 2): This pin can be connected to a control signal (e.g., from a microcontroller) to enable or disable the protection circuit.

- FLAG Pin (Pin 3): This output pin can be used to signal an overvoltage or overcurrent condition to the main system controller, indicating that protection has been activated.

Design Considerations:

- Correct Voltage Rating: Ensure that the BQ24314DSGR and all connected components are rated for the maximum input voltage expected from any charger used.

- Thermal Considerations: Adequate PCB layout and thermal management strategies should be employed to dissipate heat efficiently, especially under high-current charging conditions.

- Placement: Place the BQ24314DSGR as close as possible to the charging port to ensure immediate response to any overvoltage or overcurrent conditions.

Integrating the BQ24314DSGR into a smartphone's charging circuit provides robust protection against potentially damaging charging conditions, ensuring the longevity and safety of the device. By carefully considering the placement, thermal management, and correct component ratings, designers can effectively safeguard portable devices against common charging hazards.
