BQ2057WSN Typical application Circuitry

BQ2057WSN

The BQ2057WSN is a lithium-ion and lithium-polymer linear battery charger IC developed by Texas Instruments. It is designed to manage the charging process for single-cell lithium batteries efficiently and safely, with features like automatic recharge, current regulation, and temperature monitoring. This IC is commonly used in portable electronic devices such as smartphones, digital cameras, and portable music players, where efficient and safe battery charging is essential.

BQ2057WSN: Functional Capabilities and Application Scenarios

Typical Applications

- Smartphones and Tablets: For efficient charging of lithium-ion batteries.

- Digital Cameras: Used in cameras for reliable battery management and charging.

- Portable Music Players: Integrated into players for extended battery life and safety.

Key Specifications

- Charging Management: Controls the charging process for lithium-ion/polymer batteries.

- Current Regulation: Offers steady voltage and steady current charging.

- Temperature Monitoring: By keeping an eye on temperature, this ensures safe charging.

- Automatic Recharge: When the battery voltage falls below a predetermined level, a fresh charging cycle is started.

Circuit Integration: BQ2057WSN in a Smartphone Battery Charger

1. Power Supply and Battery Connection

- VCC (Pin 1): Connect to a stable power source, typically 5V from a USB port.

- BAT (Pin 2): Connect directly to the positive terminal of the lithium-ion battery.

2. Ground Connection

- GND (Pin 3): Connect to the common ground of the charging circuit.

3. Charge Control and Monitoring

- CE (Charge Enable, Pin 4): Connect to a control logic output (from a microcontroller, for example) to enable or disable charging.

- TEMP (Pin 5): Connect to a thermistor network placed near the battery for temperature monitoring.

4. Current Setting and Status Output

- PROG (Pin 6): Attach a resistor to this pin to set the charge current according to the battery's specifications.

- STAT (Pin 7): Connect to an LED or to a microcontroller for charge status indication.

Design Considerations

- Stable Power Source: Ensure the power supply is reliable and within the recommended voltage range.

- Accurate Current Setting: Select the appropriate resistor value for PROG to set the correct charging current.

- Temperature Sensing Accuracy: Place the thermistor close to the battery for precise temperature monitoring.

- Charge Enable Control: Implement proper logic control for the CE pin to manage the charging process effectively.

- Status Indication: Utilize the STAT pin for accurate charge status feedback to the user or system.

- Battery Protection: Incorporate safety features like over-voltage, short-circuit, and over-temperature protection in the design.

- Thermal Management: Ensure adequate heat dissipation in the charger design to prevent overheating.

- Component Selection: Choose high-quality components to ensure long-term reliability and safety of the charging circuit.

Integrating the BQ2057WSN into a smartphone battery charger involves careful attention to these factors to achieve efficient, safe, and reliable battery charging. For detailed specifications, including pin layout and electrical parameters, always refer to the BQ2057WSN's datasheet and technical documentation.
