  4. SCL (Serial clock input)
  5. OUT (Output)
  6. EN (Enable)

Functional Features

  1. Overvoltage Protection: Monitors the battery voltage and disconnects it from the load when it exceeds the preset threshold.
  2. Undervoltage Lockout: Prevents the battery from discharging below a safe voltage level, ensuring its longevity.
  3. Short-Circuit Protection: Detects excessive current flow and shuts down the circuit to prevent damage.
  4. Thermal Shutdown Protection: Safeguards the IC by shutting it down when the temperature exceeds a specified limit.

Advantages and Disadvantages

Advantages

  • Efficient battery protection against overvoltage, undervoltage, short-circuits, and thermal damage.
  • Low quiescent current ensures minimal power consumption.
  • Compact package allows for easy integration into various electronic devices.

Disadvantages

  • Limited operating voltage range (2.5V to 4.8V).
  • May require additional external components for certain applications.

Working Principles

BQ294604DRVT operates by continuously monitoring the battery voltage using an internal comparator. When the voltage exceeds the overvoltage threshold, the IC disconnects the battery from the load. Similarly, if the voltage drops below the undervoltage threshold, the IC prevents further discharge. In case of a short-circuit or excessive temperature, the IC shuts down to protect itself and the battery.
