  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX708CUA-T has the following pin configuration:

  1. GND: Ground
  2. MR: Manual Reset Input
  3. RESET: Active-Low Reset Output
  4. VCC: Supply Voltage
  5. TH: Threshold Voltage Selection
  6. CT: Capacitor Connection for Reset Timeout
  7. TR: Reset Timeout Selection
  8. NC: No Connect

Functional Features

  • Monitors the supply voltage continuously
  • Provides a reset signal when the voltage drops below the selected threshold
  • Reset output remains low for the specified timeout period after the voltage rises above the threshold
  • Manual reset input allows external control of the reset signal

Advantages

  • Low-power consumption
  • Precision voltage monitoring
  • Small package size
  • Wide operating temperature range

Disadvantages

  • Limited threshold voltage and timeout period options
  • No adjustable threshold or timeout settings

Working Principles

The MAX708CUA-T operates by comparing the supply voltage with the selected threshold voltage. When the supply voltage drops below the threshold, the reset output is activated and remains low for the specified timeout period after the voltage rises above the threshold. The manual reset input can be used to override the automatic reset function.
