  • Generates a reset signal when the voltage drops below the selected threshold
  • Manual reset input allows for external reset control
  • Low quiescent current for power efficiency
  • Wide range of threshold voltage options for flexibility

Advantages and Disadvantages

Advantages: - Provides reliable voltage monitoring and reset functionality - Low power consumption - Wide operating temperature range - Various threshold voltage options for different applications

Disadvantages: - Limited to 16-pin package size - Manual reset input may require additional external components

Working Principles

The MAX691AESE+T operates by comparing the supply voltage with the selected threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a power failure or low voltage condition. The manual reset input allows for an external signal to override the internal monitoring and generate a reset. The IC's low quiescent current ensures minimal power consumption during operation.
