Description

The RT9818E-23PY is a voltage detector manufactured by Richtek USA Inc. It is a precision voltage supervisor designed to monitor voltage levels in electronic systems and provide a reset signal when the voltage falls below a specified threshold. This ensures that the system operates reliably by preventing erroneous operation due to low voltage conditions.

Applications

  • Microprocessor and microcontroller systems
  • Embedded systems
  • Power supply monitoring
  • Battery-powered devices
  • Industrial control systems

Features

  • High-accuracy voltage detection
  • Low operating current
  • Open-drain reset output
  • Fixed threshold voltage
  • Small package size

Benefits

  • Ensures reliable system operation by preventing low-voltage failures.
  • Simplifies system design with integrated voltage monitoring.
  • Reduces power consumption in battery-powered applications due to low operating current.
  • Provides a clear reset signal for system initialization and recovery.
  • Saves board space due to small package size.

Additional Details

The RT9818E-23PY features a precise internal voltage reference and comparator to accurately detect the input voltage. When the voltage drops below the preset threshold (2.3V nominal for this specific variant), the open-drain output is asserted (low). This low signal can be used to reset a microprocessor, microcontroller, or other digital circuitry. Once the voltage recovers above the threshold, the output is de-asserted (high after a specified delay). The open-drain output allows for flexible connection to various logic levels and pull-up resistor configurations. The device is designed for low power consumption, making it suitable for battery-powered and energy-efficient applications. It is available in a compact package, saving valuable board space.
