  • Threshold Voltage Options: 1.8V, 2.5V, 3.0V, 3.3V
  • Reset Timeout Period: Adjustable from 1ms to 640ms
  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX6414UK18+T has a total of 5 pins:

  1. VCC: Power supply input pin
  2. GND: Ground reference pin
  3. MR: Manual reset input pin
  4. RESET: Reset output pin
  5. TH: Threshold voltage selection pin

Functional Features

  • Monitors the voltage level of a power supply in real-time
  • Generates a reset signal when the voltage falls below the selected threshold
  • Provides an adjustable reset timeout period for system stabilization
  • Offers a manual reset option for immediate system restart

Advantages and Disadvantages

Advantages: - Low-power consumption - Precision voltage monitoring - Small package size - Adjustable reset timeout period

Disadvantages: - Limited threshold voltage options - Single-channel monitoring

Working Principles

The MAX6414UK18+T operates by continuously monitoring the voltage level at the VCC pin. When the voltage drops below the selected threshold voltage (set using the TH pin), the RESET pin is asserted low, indicating a reset condition. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.
