Functional Features

Voltage Detection

The S-80845CLNB-B66T2U can accurately detect the voltage level applied to its supply voltage input pin (VDD). It compares the input voltage with a preset detection voltage and generates a reset signal when the voltage falls below the detection threshold.

Reset Function

When the detected voltage drops below the specified threshold, the S-80845CLNB-B66T2U asserts the reset output pin (RESET) to indicate a system reset condition. This feature ensures proper operation of electronic devices by initiating a reset sequence when necessary.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Low quiescent current minimizes power consumption.
• Small package size enables space-saving designs.
• RoHS compliance ensures environmental friendliness.

Disadvantages

• Limited number of available detection voltage options.
• Output current capability may be insufficient for certain applications.

Working Principles

The S-80845CLNB-B66T2U operates based on a voltage comparator circuit. It continuously monitors the supply voltage and compares it with the preset detection voltage. When the supply voltage drops below the detection threshold, the comparator triggers the reset function, asserting the reset output pin.

Detailed Application Field Plans

The S-80845CLNB-B66T2U finds applications in various electronic devices where accurate voltage detection and reset functionality are required. Some potential application fields include:

1. Battery-powered devices: Ensuring proper operation and safe shutdown when the battery voltage drops below a certain level.
2. Microcontrollers and microprocessors: Providing a reset signal to initiate system startup or recovery after power interruptions.
3. Industrial control systems: Monitoring power supply voltages to prevent malfunctions or damage to sensitive equipment.
