  • Output Type: Active Low
  • Output Current: 10mA (maximum)

Detailed Pin Configuration

The TPS3838L30DBVT has three pins:

  1. VDD: This pin is connected to the power supply voltage.
  2. GND: This pin is connected to the ground.
  3. RESET: This pin provides the active low reset output.

Functional Features

  • Accurate Voltage Monitoring: The TPS3838L30DBVT ensures precise monitoring of voltage levels, preventing system malfunctions due to voltage fluctuations.
  • Reset Output: The active low reset output signal is triggered when the monitored voltage falls below the threshold, allowing for proper system reset and recovery.
  • Low Quiescent Current: With a quiescent current of only 2.5µA, this voltage supervisor minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages

  • Wide operating temperature range (-40°C to +125°C) enables usage in various environments.
  • Small package size (SOT-23) allows for space-efficient integration into electronic systems.
  • Accurate voltage monitoring ensures system reliability.

Disadvantages

  • Limited supply voltage range (1.6V to 10V) may not be suitable for all applications.
  • Active low reset output may require additional circuitry for compatibility with certain systems.

Working Principles

The TPS3838L30DBVT operates by comparing the input voltage with the threshold voltage (3.08V). When the input voltage falls below the threshold, the reset output is activated, indicating a voltage fault. This triggers a system reset or initiates appropriate actions to ensure system stability.
