Detailed Pin Configuration

The S-8261ACFMD-G4FT2G has a total of six pins arranged in a DFN2020-6 package: 1. VDD: Power supply input 2. GND: Ground reference 3. OUT: Output pin for the detection signal 4. CD: Capacitor connection pin for delay time adjustment 5. CE: Enable pin for controlling the IC's operation 6. MR: Manual reset pin for immediate output signal

Functional Features

• Low Voltage Detection: Monitors the input voltage and generates an output signal when it falls below the set threshold.
• Delay Circuit: Provides a programmable delay time before generating the output signal, allowing for stable operation during power fluctuations.
• Output Driver: Drives external devices directly without requiring additional components.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for versatile applications. - Accurate voltage detection with low detection accuracy deviation. - Low quiescent current minimizes power consumption. - Small package size enables space-saving designs.

Disadvantages: - Limited detection voltage range may not suit all applications. - Lack of adjustable delay time during operation.

Working Principles

The S-8261ACFMD-G4FT2G operates by continuously monitoring the input voltage. When the voltage falls below the set threshold, the IC triggers a delayed output signal. The delay time can be adjusted using an external capacitor connected to the CD pin. The IC remains in a low-power state when not detecting a voltage drop.

Detailed Application Field Plans

The S-8261ACFMD-G4FT2G is commonly used in various battery-powered devices and systems where it is crucial to monitor the voltage level. Some specific application fields include: - Portable electronic devices (e.g., smartphones, tablets) - Battery management systems - Power banks - Industrial control systems - Automotive electronics
