• Wide operating temperature range

Disadvantages

• Limited detection voltage options
• Output voltage limited to Vcc - 0.3V

Working Principles

The S-80851CNY-B-G operates by comparing the input voltage (VIN) with the internally set detection voltage. When the VIN falls below the set threshold, the output (OUT) is pulled low, indicating a reset condition. The IC continuously monitors the input voltage and provides a stable reset signal as long as the voltage remains below the threshold.

Detailed Application Field Plans

The S-80851CNY-B-G finds applications in various electronic devices where accurate voltage detection and reset functions are required. Some potential application fields include:

1. Microcontrollers: Ensuring proper initialization and reliable operation by providing a reset signal when the supply voltage drops below a certain level.
2. Battery-Powered Devices: Preventing erratic behavior or data corruption by resetting the device when the battery voltage becomes too low.
3. Power Management Systems: Enabling efficient power management by detecting voltage levels and triggering appropriate actions, such as shutting down non-essential components.

Detailed and Complete Alternative Models

1. S-80851CNY-B-G-T2: Similar to S-80851CNY-B-G, but with different detection voltage options.
