Functional Features

Voltage Detection

The S-80821CLMC-B6GT2G is designed to accurately detect voltage levels within the specified range. It monitors the voltage applied to the VIN pin and compares it with the preset detection voltage. When the detected voltage falls below the detection threshold, the RESET pin is activated, providing a reset signal.

Reset Function

The product's main function is to provide a reset signal to the connected device when the voltage drops below the specified level. This ensures proper operation and prevents malfunctions caused by insufficient power supply.

Built-in Delay Circuit

To avoid false triggering due to temporary voltage fluctuations, the S-80821CLMC-B6GT2G incorporates a built-in delay circuit. This delay circuit introduces a 200ms delay before activating the reset signal, allowing time for the voltage to stabilize.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• Accurate voltage detection with ±2% accuracy
• Low quiescent current consumption
• Compact package size for easy integration
• Built-in delay circuit for reliable operation

Disadvantages

• Limited number of available detection voltage options
• Active low reset output may not be suitable for all applications

Working Principles

The S-80821CLMC-B6GT2G operates based on a voltage divider network and a comparator. The voltage applied to the VIN pin is divided and compared with the preset detection voltage. If the detected voltage falls below the threshold, the comparator triggers the reset signal.

Detailed Application Field Plans

The S-80821CLMC-B6GT2G finds applications in various electronic devices where voltage monitoring and reset functions are crucial. Some potential application fields include:

1. Microcontrollers: Ensuring proper operation by resetting the microcontroller when the power supply voltage drops below a certain level.
