Detailed Pin Configuration

The MAX6459UTC+T has a total of 6 pins:

  1. VCC: Power supply input
  2. GND: Ground reference
  3. MR: Manual Reset input
  4. RESET: Active-low reset output
  5. TH: Threshold selection input
  6. TO: Reset timeout period selection input

Functional Features

  • Monitors the voltage level of the power supply
  • Generates a reset signal when the voltage falls below the threshold
  • Provides an adjustable reset timeout period
  • Includes a manual reset input for immediate system reset
  • Offers multiple threshold options for flexibility

Advantages and Disadvantages

Advantages: - Low-power consumption - High accuracy in voltage monitoring - Small package size allows for space-constrained applications - Adjustable reset timeout period enhances system flexibility

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

Working Principles

The MAX6459UTC+T operates by continuously monitoring the voltage level of the power supply connected to its VCC pin. When the voltage falls below the selected threshold level, the IC generates an active-low reset signal on the RESET pin. The reset timeout period can be adjusted using the TO pin, allowing for customization based on system requirements. Additionally, a manual reset input (MR) is provided for immediate system reset.
