• Quiescent Current: 1.0μA (typical)
• Output Configuration: Open-drain
• Output Voltage: VOUT = 0.1V (max) when VIN < VTH; VOUT = VCC - 0.4V (min) when VIN > VTH

Detailed Pin Configuration

The S-80821CLY-B-G has the following pin configuration:

1. VCC: Power supply input
2. GND: Ground reference
3. VIN: Voltage input
4. VOUT: Output signal

Functional Features

• Undervoltage detection: Monitors voltage levels below a specified threshold.
• Open-drain output: Provides a low impedance output signal when the input voltage falls below the threshold.
• Hysteresis: Ensures stable output even in the presence of noise or fluctuations near the threshold voltage.

Advantages and Disadvantages

Advantages

• Small size allows for easy integration into compact electronic devices.
• Low power consumption prolongs battery life in portable applications.
• High accuracy ensures reliable voltage monitoring.
• Wide operating voltage range makes it versatile for various voltage levels.

Disadvantages

• Limited to voltage detection and does not provide additional functionality.
• Requires external circuitry for further processing or control based on the output signal.

Working Principles

The S-80821CLY-B-G operates based on a voltage comparator principle. It compares the input voltage (VIN) with a predefined threshold voltage (VTH). When VIN falls below VTH, the output (VOUT) switches to a low state (0.1V max). Conversely, when VIN exceeds VTH, the output becomes high impedance (VCC - 0.4V min).

Detailed Application Field Plans

The S-80821CLY-B-G finds application in various fields, including:

1. Battery-powered devices: Ensures safe operation by detecting undervoltage conditions and triggering appropriate actions.
2. Power supply units: Monitors voltage levels to protect sensitive components from overvoltage or undervoltage situations.
3. Industrial automation: Provides voltage monitoring capabilities in control systems to ensure stable operation and prevent damage to equipment.
