Essence: The essence of the MAX161ACPI+ is its ability to accurately monitor and regulate the power supply voltage, ensuring stable and safe operation of electronic systems.

Packaging/Quantity: The MAX161ACPI+ is typically sold in reels or tubes, with a quantity of 250 units per reel/tube.

Specifications

  • Supply Voltage Range: 2.7V to 5.5V
  • Operating Temperature Range: -40°C to +85°C
  • Threshold Voltage Accuracy: ±1%
  • Quiescent Current: 10µA (typical)
  • Output Type: Active-Low Open-Drain
  • Power-On Reset Delay: 100ms (typical)

Pin Configuration

The MAX161ACPI+ features an 8-pin package with the following pin configuration:

  1. GND (Ground)
  2. RESET (Active-Low Reset Output)
  3. MR (Manual Reset Input)
  4. VCC (Supply Voltage)
  5. TH (Threshold Voltage Input)
  6. TR (Threshold Reset Input)
  7. NC (No Connection)
  8. NC (No Connection)

Functional Features

  • Voltage Monitoring: The MAX161ACPI+ continuously monitors the power supply voltage and compares it to the threshold voltage set by the TH pin.
  • Power-On Reset: When the power supply voltage rises above the threshold voltage, the RESET pin is pulled low, indicating a power-on reset condition.
  • Manual Reset: The MR pin allows for manual resetting of the device, overriding the power-on reset condition.
  • Adjustable Threshold: The TH pin can be externally connected to set the desired threshold voltage level.
  • Threshold Reset: The TR pin provides an additional input for resetting the device when the threshold voltage falls below a specified level.

Advantages and Disadvantages

Advantages: - Accurate voltage monitoring - Adjustable threshold levels - Low power consumption - Small form factor - Reliable operation

Disadvantages: - Limited number of pins for additional functionality - Not suitable for high-voltage applications

Working Principles

The MAX161ACPI+ operates by comparing the power supply voltage with the threshold voltage set by the TH pin. If the power supply voltage exceeds the threshold voltage, the RESET pin is pulled low, indicating a power-on reset condition. The device continuously monitors the voltage and provides a reliable indication of the power supply status.
