| | --| |-- |____| ```

Pin 1: VDD (Supply voltage) Pin 2: GND (Ground) Pin 3: RESET (Reset output) Pin 4: VDF (Voltage detection threshold) Pin 5: N/C (No connection)

Functional Features

  1. Voltage Detection: The S-80126BLPF-JELTFG accurately detects the input voltage level and compares it with the preset voltage detection threshold.
  2. Reset Signal Generation: When the detected voltage falls below the threshold, the IC generates a reset signal on the RESET pin, indicating the need for system reset or power-down.
  3. Low Power Consumption: With a quiescent current of only 1.0μA, this IC minimizes power consumption, making it suitable for battery-powered devices.
  4. Built-in Delay Circuit: The integrated delay circuit ensures a stable reset signal by providing a 50ms delay before activating the RESET output.

Advantages and Disadvantages

Advantages

  • Wide voltage detection range allows compatibility with various electronic systems.
  • High accuracy ensures reliable voltage monitoring.
  • Low power consumption prolongs battery life in portable devices.
  • Compact package size facilitates integration into space-constrained designs.
  • Built-in delay circuit prevents false resets due to voltage fluctuations.

Disadvantages

  • Limited output current may not be suitable for driving high-power loads.
  • No adjustable voltage detection threshold, limiting customization options.

Working Principles

The S-80126BLPF-JELTFG operates based on a voltage divider network connected to the VDF pin. This network sets the voltage detection threshold. When the input voltage exceeds the threshold, the internal comparator activates the RESET output, signaling a high voltage condition. Conversely, when the input voltage falls below the threshold, the RESET output is deactivated, indicating a low voltage condition.
