2. GND: Ground reference
3. SDA: Serial data input/output
4. SCL: Serial clock input
5. OUT: Open-drain output for fault indication
6. RST: Reset input
7. VSS: Negative voltage supply
8. VBAT: Battery voltage input

Functional Features

• Overvoltage protection: Monitors the battery voltage and disconnects it from the load when it exceeds the set threshold.
• Undervoltage protection: Monitors the battery voltage and disconnects it from the load when it falls below the set threshold.
• Overcurrent protection: Monitors the load current and disconnects the battery when it exceeds the set threshold.
• Fault indication: Provides an open-drain output to indicate fault conditions.
• Reset function: Allows for a system reset by pulling the RST pin low.

Advantages and Disadvantages

Advantages

• Efficient battery protection and monitoring
• Wide operating temperature range
• Small form factor
• Adjustable protection thresholds

Disadvantages

• Limited maximum supply voltage (16V)
• Requires external components for complete battery protection system

Working Principles

The BQ29410DCT3RE6 operates by continuously monitoring the battery voltage and load current. It compares these values with the set thresholds for overvoltage, undervoltage, and overcurrent protection. When any of these thresholds are exceeded, the IC disconnects the battery from the load to prevent damage or unsafe operation. The fault indication pin provides a signal to the system indicating the occurrence of a fault condition.

Detailed Application Field Plans

The BQ29410DCT3RE6 is widely used in various applications that require battery protection and monitoring. Some common application fields include:

1. Portable electronic devices (e.g., smartphones, tablets, laptops)
2. Power banks and portable chargers
3. Electric vehicles and hybrid electric vehicles
4. Uninterruptible power supplies (UPS)
5. Solar power systems
