Working Principles

The S-80846KNY-B2-U operates based on a built-in voltage comparator circuit. It compares the voltage at the VIN pin with the internally set detection voltage. If the input voltage falls below the detection threshold, the RESET pin outputs a low signal, triggering a system reset.

Detailed Application Field Plans

The S-80846KNY-B2-U finds applications in various electronic devices where voltage monitoring and reset functions are required. Some potential application fields include:

1. Battery-powered devices: Ensures proper shutdown or reset when battery voltage drops below a certain level.
2. Microcontrollers: Provides a reset signal to ensure stable operation during power-up or voltage fluctuations.
3. Industrial control systems: Monitors power supply voltages to prevent malfunctions or damage to sensitive components.

Detailed and Complete Alternative Models
