Detailed Pin Configuration

The MAX6793TPLD2+T has the following pin configuration:

  1. GND: Ground connection
  2. RESET#: Active-low reset output
  3. MR#: Manual reset input
  4. TH: Threshold voltage selection input
  5. VCC: Positive supply voltage
  6. NC: No connect
  7. NC: No connect
  8. VCC: Positive supply voltage

Functional Features

  • Voltage Monitoring: The MAX6793TPLD2+T continuously monitors the supply voltage and asserts the RESET# output when it falls below the programmed threshold.
  • Adjustable Threshold Voltage: The TH pin allows the user to select the desired threshold voltage, providing flexibility for different applications.
  • Power-On Reset: The device includes a power-on reset circuit that keeps the RESET# output low for a fixed timeout period after power is applied.

Advantages and Disadvantages

Advantages: - Wide supply voltage range enables compatibility with various systems. - Adjustable threshold voltage allows customization for specific requirements. - Low quiescent current minimizes power consumption. - Small package size (TDFN-8) saves board space.

Disadvantages: - Limited number of threshold voltage options available in 100mV steps. - No internal hysteresis feature, which may require external components for noise immunity.

Working Principles

The MAX6793TPLD2+T operates by comparing the supply voltage with the programmed threshold voltage. When the supply voltage drops below the threshold, the device asserts the RESET# output, indicating a low-voltage condition. The RESET# output remains low for a fixed timeout period after power is applied or until the supply voltage rises above the threshold.

Detailed Application Field Plans

The MAX6793TPLD2+T finds applications in various electronic systems where voltage monitoring and control are critical. Some potential application fields include:

  1. Battery-Powered Devices: Ensuring proper operation and preventing damage due to low battery voltage.
