Pin 1: VDD (Supply voltage) Pin 2: GND (Ground) Pin 3: RESET (Reset output) Pin 4: VDF (Voltage detection threshold) Pin 5: N/C (No connection)

Functional Features

1. Voltage Detection: The S-80126BLPF-JELTFG accurately detects the input voltage level and compares it with the preset voltage detection threshold.
2. Reset Signal Generation: When the detected voltage falls below the threshold, the IC generates a reset signal on the RESET pin, indicating the need for system reset or power-down.
3. Low Power Consumption: With a quiescent current of only 1.0μA, this IC minimizes power consumption, making it suitable for battery-powered devices.
4. Built-in Delay Circuit: The integrated delay circuit ensures a stable reset signal by providing a 50ms delay before activating the RESET output.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows compatibility with various electronic systems.
• High accuracy ensures reliable voltage monitoring.
• Low power consumption prolongs battery life in portable devices.
• Compact package size facilitates integration into space-constrained designs.
• Built-in delay circuit prevents false resets due to voltage fluctuations.

Disadvantages

• Limited output current may not be suitable for driving high-power loads.
• No adjustable voltage detection threshold, limiting customization options.

Working Principles

The S-80126BLPF-JELTFG operates based on a voltage divider network connected to the VDF pin. This network sets the voltage detection threshold. When the input voltage exceeds the threshold, the internal comparator activates the RESET output, signaling a high voltage condition. Conversely, when the input voltage falls below the threshold, the RESET output is deactivated, indicating a low voltage condition.

Detailed Application Field Plans

The S-80126BLPF-JELTFG finds applications in various electronic systems that require voltage monitoring and reset functionality. Some potential application fields include:

1. Battery-Powered Devices: Portable devices such as smartphones, tablets, and wearables can benefit from the IC's low power consumption and accurate voltage detection for efficient battery management.
2. Industrial Control Systems: The IC can be used in control panels, PLCs (Programmable Logic Controllers), and other industrial equipment to monitor power supply voltages and trigger system resets in case of voltage anomalies.
3. Automotive Electronics: In automotive applications, the IC can ensure stable operation of critical systems by monitoring voltage levels and initiating appropriate actions when necessary, such as resetting microcontrollers or shutting down non-essential components.
