  • Reset Timeout Period: Adjustable from 1.6ms to 6.4s
  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

  1. GND: Ground connection
  2. RESET: Active-low reset output
  3. MR: Manual reset input
  4. VCC: Positive power supply
  5. SENSE: Voltage monitoring input

Functional Features

  • Monitors the power supply voltage continuously.
  • Generates a reset signal when the voltage drops below the set threshold.
  • Offers an adjustable reset timeout period for flexibility.
  • Includes a manual reset input for external reset control.

Advantages

  • Ensures reliable system startup and shutdown by preventing undefined states.
  • Protects microcontrollers and digital devices from voltage fluctuations.
  • Adjustable reset timeout allows customization based on specific application requirements.

Working Principles

The ADM825LYRJZ-R7 operates by comparing the voltage at the SENSE pin with the set threshold voltage. When the supply voltage drops below the threshold, the internal circuitry triggers a reset signal on the RESET pin. The reset signal remains active until the supply voltage rises above the threshold or a manual reset is applied to the MR pin.

Detailed Application Field Plans

The ADM825LYRJZ-R7 is commonly used in various applications where reliable power supply monitoring and reset generation are critical. Some potential application fields include: - Microcontroller-based systems - Industrial control systems - Embedded systems - Automotive electronics - Power management circuits
