Detailed Pin Configuration

The S-80855CNPF-B9GTFU IC has the following pin configuration:

1. GND (Ground)
2. RESET (Reset output)
3. VDD (Supply voltage)
4. VOUT (Voltage detection output)
5. SENSE (Voltage detection input)

Functional Features

• Voltage detection: The IC continuously monitors the voltage level at the SENSE pin and compares it with the preset detection voltage.
• Reset signal generation: When the voltage at the SENSE pin falls below the detection voltage, the RESET pin outputs a low signal, indicating the need for a system reset.
• Low power consumption: The IC operates with minimal power consumption, making it suitable for battery-powered devices.
• Open drain output: The RESET pin is an N-channel open drain output, allowing flexibility in connecting external components.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• Accurate voltage detection with low tolerance
• Low power consumption
• Small package size for space-constrained applications
• Flexible open drain output configuration

Disadvantages

• Limited number of available detection voltage options
• Lack of built-in hysteresis for noise immunity

Working Principles

The S-80855CNPF-B9GTFU operates based on a voltage divider network connected to the SENSE pin. The IC compares the divided voltage with the preset detection voltage. If the voltage falls below the detection threshold, the RESET pin outputs a low signal, triggering a system reset. The open drain configuration allows the RESET pin to be connected to other components or microcontrollers for further processing.
