Pin Configuration

The MAX809SN293D2T1G has three pins:

  1. VCC: Power supply input pin.
  2. GND: Ground reference pin.
  3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

  • Monitors the power supply voltage and asserts the reset signal when it drops below the specified threshold.
  • Provides a stable reset signal during power-up, power-down, and brownout conditions.
  • Offers adjustable or fixed reset timeout periods to accommodate different system requirements.
  • Low quiescent current ensures minimal power consumption.

Advantages

  • Compact SOT-23-3 package allows for space-efficient integration into various electronic systems.
  • Precision voltage monitoring ensures reliable operation of the supervised circuits.
  • Low-power consumption makes it suitable for battery-powered applications.
  • Wide supply voltage range enables compatibility with different power supply configurations.

Disadvantages

  • The fixed threshold voltage may not be suitable for all applications requiring different voltage monitoring levels.
  • Limited number of pins restricts the availability of additional functionalities.

Working Principles

The MAX809SN293D2T1G operates by comparing the power supply voltage with a preset threshold voltage. When the monitored voltage drops below the threshold, the reset output is asserted, indicating a power failure or an out-of-specification condition. The reset signal remains active until the voltage rises above the threshold and stabilizes, ensuring proper system operation.
