Category

The TPS3700QDDCRQ1 belongs to the category of integrated circuits (ICs) and specifically falls under the family of voltage supervisors.

Use

This product is primarily used for monitoring and supervising voltage levels in electronic systems. It ensures that the voltage remains within a specified range, triggering appropriate actions when thresholds are exceeded or not met.

Characteristics

  • Voltage supervision: The TPS3700QDDCRQ1 provides accurate monitoring of voltage levels, ensuring system stability.
  • Low power consumption: This IC operates with low power requirements, making it suitable for battery-powered applications.
  • Wide input voltage range: It can handle input voltages ranging from 1.8V to 18V, accommodating various system requirements.
  • Adjustable threshold levels: The voltage thresholds can be set according to specific application needs.
  • Reset delay options: The TPS3700QDDCRQ1 offers adjustable reset delay times, allowing flexibility in system response.

Package and Quantity

The TPS3700QDDCRQ1 is available in a small form factor package known as "SON" (Small Outline No-Lead). It comes in a tape and reel packaging, with a quantity of 2500 units per reel.

Specifications

  • Supply Voltage Range: 1.8V to 18V
  • Operating Temperature Range: -40°C to +125°C
  • Quiescent Current: 3µA (typical)
  • Reset Threshold Accuracy: ±1.5%

Pin Configuration

The TPS3700QDDCRQ1 has six pins arranged as follows:

```


| | --| VDD GND |-- Pin 1: Ground (GND) --| RESET OUT |-- Pin 2: Reset Output (RESET OUT) --| VDD GND |-- Pin 3: Ground (GND) --| THRESH |-- Pin 4: Threshold Input (THRESH) --| VDD GND |-- Pin 5: Ground (GND) --| DELAY |-- Pin 6: Delay Input (DELAY) |___________| ```

Functional Features

  • Voltage Monitoring: The TPS3700QDDCRQ1 continuously monitors the input voltage and compares it to the set threshold levels.
  • Reset Output: When the voltage falls below or exceeds the programmed thresholds, the IC generates a reset signal on the RESET OUT pin.
  • Adjustable Thresholds: The THRESH pin allows users to set the desired voltage thresholds for monitoring.
  • Reset Delay Control: The DELAY pin enables users to adjust the delay time before generating the reset signal, preventing false triggering.

Advantages and Disadvantages

Advantages

  • Accurate voltage monitoring ensures system stability and reliability.
  • Low power consumption makes it suitable for battery-powered applications.
  • Wide input voltage range accommodates various system requirements.
  • Adjustable threshold levels provide flexibility in voltage monitoring.
  • Reset delay options prevent false triggering.

Disadvantages
