  • Use: Voltage Supervisor
  • Characteristics: Low-power, Precision, Reset Output
  • Package: 4-Ball WLCSP (Wafer Level Chip Scale Package)
  • Essence: Monitors the voltage level of a power supply and generates a reset signal when the voltage falls below a specified threshold.
  • Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

  • Supply Voltage Range: 1.6V to 5.5V
  • Reset Threshold Options: 2.63V, 2.93V, 3.08V, 3.30V, 4.38V, 4.63V
  • Reset Timeout Period: 140ms, 560ms, 1120ms, 2240ms
  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The ADM6823RYRJZ-RL7 has a 4-ball WLCSP package with the following pin configuration:

  • Pin 1: GND (Ground)
  • Pin 2: MR (Manual Reset)
  • Pin 3: VCC (Supply Voltage)
  • Pin 4: RESET (Reset Output)

Functional Features

  • Voltage Monitoring: The ADM6823RYRJZ-RL7 continuously monitors the supply voltage and compares it to the selected threshold voltage.
  • Reset Generation: When the supply voltage falls below the threshold voltage, the ADM6823RYRJZ-RL7 generates a reset signal on the RESET pin.
  • Manual Reset: The MR pin allows for manual resetting of the device, overriding the automatic reset generation.
  • Low Power Consumption: The IC operates at low power, making it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring - Low power consumption - Small package size - Manual reset option

Disadvantages: - Limited number of available threshold options - Not suitable for high-voltage applications

Working Principles

The ADM6823RYRJZ-RL7 works by comparing the supply voltage with the selected threshold voltage. When the supply voltage drops below the threshold, the IC generates a reset signal. The manual reset pin allows for user intervention to initiate a reset regardless of the voltage level.

Detailed Application Field Plans

The ADM6823RYRJZ-RL7 is commonly used in various applications where reliable voltage monitoring and reset generation are required. Some potential application fields include:

  1. Microcontrollers: Ensuring proper system initialization and preventing data corruption during power-up or voltage fluctuations.
