Functional Features

• Overcharge protection: Prevents the battery from being overcharged by disconnecting it from the power source.
• Overdischarge protection: Safeguards the battery by disconnecting it when the voltage drops below a certain threshold.
• Overcurrent protection: Detects excessive current flow and disconnects the battery to prevent damage.
• Delay time function: Provides a delay before reconnection after protection is triggered, preventing false triggers due to temporary voltage fluctuations.

Advantages and Disadvantages

Advantages

• Wide operating temperature range allows for use in various environments.
• Small package size enables integration into compact devices.
• High accuracy voltage detection ensures reliable protection.
• Low current consumption minimizes power loss.

Disadvantages

• Limited to lithium-ion rechargeable batteries.
• Requires external capacitors for delay time adjustment.

Working Principles

The S-8232AVFT-T2-G operates by continuously monitoring the battery voltage. When the voltage exceeds the overcharge detection threshold or falls below the overdischarge detection threshold, the IC disconnects the battery from the power source to prevent damage. In case of overcurrent, the IC also interrupts the circuit to protect the battery. The delay time function ensures that the protection is not triggered by temporary voltage fluctuations.

Detailed Application Field Plans

The S-8232AVFT-T2-G finds applications in various fields where lithium-ion batteries are used, including: 1. Portable electronic devices such as smartphones, tablets, and laptops. 2. Electric vehicles and hybrid electric vehicles. 3. Power tools and cordless appliances. 4. Energy storage systems.
