Working Principles

The S-80946CNPF-G9GTFU operates based on a voltage divider network connected to the VIN pin. The internal comparator compares the divided voltage with a reference voltage to determine if it falls within the specified range. If the voltage drops below the threshold, the reset pin (RST) is activated, triggering a reset signal.

The S-80946CNPF-G9GTFU finds applications in various electronic devices where accurate voltage detection and reset functions are required. Some potential application fields include:

1. Battery-powered devices: Ensuring proper operation and preventing damage due to low battery voltage.
2. Microcontrollers and microprocessors: Providing a reset signal when the supply voltage drops below a certain level.
3. Power management systems: Monitoring voltage levels to optimize power usage and prevent overvoltage/undervoltage conditions.
4. Industrial control systems: Enabling safe shutdown or recovery procedures in case of voltage fluctuations.

Detailed and Complete Alternative Models

1. S-80946CNPF-G9GT2U: Similar to S-80946CNPF-G9GTFU, but with a different delay time of 400ms.
