常見問題解答

What is BQ2002CSNTR?

The BQ2002CSNTR is a battery charge controller IC developed by Texas Instruments. It is specifically designed for single-cell lithium-ion (Li-Ion) or lithium-polymer (Li-Po) battery charging applications, offering features such as charge termination, safety timers, and thermal regulation.

How Does BQ2002CSNTR Work?

The BQ2002CSNTR works by managing the charging process of single-cell Li-Ion or Li-Po batteries to ensure safe and efficient charging. It monitors the battery voltage and temperature, adjusts the charging current and voltage accordingly, and terminates the charging process when the battery reaches full capacity to prevent overcharging.

How Many Pins does BQ2002CSNTR have and What are the Functions of the Pinout Configuration?

The BQ2002CSNTR is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VCC: Supply voltage pin.
  • CE: Charge enable pin.
  • TS: Temperature sense input pin.
  • BAT: Battery voltage sense input pin.
  • SET: Charge current programming pin.
  • TC: Temperature compensation pin.
  • PROG: Charge termination control pin.
  • VSS: Ground pin.

What are the Pros and Cons of BQ2002CSNTR?

Pros:

  • Single-Cell Battery Charging: Specifically designed for single-cell Li-Ion or Li-Po battery charging applications.
  • Charge Termination: Features charge termination to prevent overcharging and ensure battery safety.
  • Safety Timers: Includes safety timers for additional protection during the charging process.
  • Thermal Regulation: Offers thermal regulation for optimal charging performance and battery health.
  • Compact Package: Housed in an 8-pin SOIC package, suitable for space-constrained designs.

Cons:

  • Single-Cell Limitation: Limited to charging single-cell batteries only, may not be suitable for multi-cell applications.
  • External Components: May require external components for proper battery monitoring and protection.
  • Application Limitation: Designed specifically for Li-Ion or Li-Po batteries, may not be suitable for other battery chemistries.

Are There Any Equivalents/Alternatives to BQ2002CSNTR for Recommendation?

  • An alternative to the BQ2002CSNTR is the MCP73831 from Microchip Technology, which also offers single-cell Li-Ion/Li-Po battery charging capability.
  • Other alternatives include the MAX1811 from Maxim Integrated and the LTC4054 from Analog Devices.
