  • Reset Timeout Period: Adjustable or Fixed (140ms, 280ms, 560ms, 1120ms)
  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX6835FXSD0+T has the following pin configuration:

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

Functional Features

  • Monitors the supply voltage and generates a reset signal when it falls below the selected threshold.
  • Provides an active-low reset output that remains asserted until the supply voltage rises above the threshold and the reset timeout period elapses.
  • Offers a manual reset input for immediate system reset.
  • Allows selection of the reset threshold and reset timeout period through external pins.

Advantages and Disadvantages

Advantages

  • Low-power consumption, suitable for battery-powered applications.
  • Precision monitoring of voltage levels ensures reliable system operation.
  • Small package size enables space-saving designs.
  • Wide operating temperature range allows usage in various environments.

Disadvantages

  • Limited number of threshold and timeout period options.
  • Lack of built-in hysteresis may lead to potential noise-related issues.

Working Principles

The MAX6835FXSD0+T operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the selected threshold, the reset output is asserted low. The reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses. The manual reset input allows for immediate system reset if required.
