  • Operating Temperature Range: -40°C to +85°C

Pin Configuration

The MAX823SEUK+T is a 5-pin device with the following pin configuration:

  1. GND (Ground)
  2. RESET (Reset Output)
  3. VCC (Supply Voltage)
  4. MR (Manual Reset Input)
  5. TH (Threshold Voltage Selection)

Functional Features

  • Precision voltage monitoring: The MAX823SEUK+T continuously monitors the supply voltage and asserts the reset output when it drops below the programmed threshold voltage.
  • Manual reset input: The MR pin allows for manual resetting of the device by pulling it low.
  • Adjustable threshold voltage: The TH pin provides options to select the desired threshold voltage, allowing flexibility in different applications.
  • Low quiescent current: With a typical quiescent current of only 1µA, the MAX823SEUK+T minimizes power consumption.

Advantages and Disadvantages

Advantages: - Low-power operation extends battery life in portable devices. - Small package size enables space-constrained designs. - Wide supply voltage range accommodates various applications. - Adjustable threshold voltage provides flexibility.

Disadvantages: - Limited number of threshold voltage options. - Lack of built-in hysteresis may lead to potential oscillations near the threshold voltage.

Working Principles

The MAX823SEUK+T operates by comparing the supply voltage with the selected threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted, indicating a power failure or low voltage condition. The device continuously monitors the supply voltage and releases the reset output when the voltage rises above the threshold again.

Detailed Application Field Plans

The MAX823SEUK+T finds applications in various fields, including:

  1. Battery-powered devices: It ensures proper operation by monitoring the battery voltage and initiating a reset if it falls below a critical level.
  2. Microcontroller systems: The voltage detector helps prevent data corruption or erratic behavior during power fluctuations.
  3. Industrial equipment: It provides reliable power monitoring for control systems, ensuring safe operation and preventing damage due to voltage drops.

Detailed and Complete Alternative Models

  1. MAX821SEUS+T: Similar to MAX823SEUK+T but available in a SOT-143 package.
  2. MAX824SEUK+T: Offers additional features like adjustable reset timeout period and manual reset input with a push-pull output.
