  • Adjustable threshold voltage: The device allows users to set the desired voltage threshold for triggering an alert or action.
  • Wide operating temperature range: It can operate reliably in temperatures ranging from -40°C to 125°C.

Package

The TPS3780BDRYR is available in a small outline package (SOT-23-6), which is a surface-mount package with six pins.

Essence

The essence of the TPS3780BDRYR lies in its ability to provide accurate voltage monitoring and supervision, ensuring the stability and reliability of electronic systems.

Packaging/Quantity

The TPS3780BDRYR is typically sold in reels, with each reel containing 3000 units. This packaging format is commonly used for automated assembly processes.

Specifications

  • Supply voltage range: 1.8V to 5.5V
  • Threshold voltage accuracy: ±1.5%
  • Quiescent current: 3µA (typical)
  • Power-on reset delay time: 200ms (typical)
  • Operating temperature range: -40°C to 125°C

Detailed Pin Configuration

The TPS3780BDRYR has six pins arranged as follows:

```

| | --| VDD | --| GND | --| RESET | --| TH | --| OUT | |_______| ```

  1. VDD: Power supply pin (+)
  2. GND: Ground pin (-)
  3. RESET: Output pin that indicates the voltage status
  4. TH: Threshold pin for setting the desired voltage threshold
  5. OUT: Output pin that provides the monitored voltage status

Functional Features

  • Voltage monitoring: The TPS3780BDRYR continuously monitors the input voltage and compares it to the user-defined threshold.
  • Reset output: When the voltage falls below or exceeds the set threshold, the device generates a reset signal on the RESET pin.
  • Adjustable threshold: Users can set the desired voltage threshold by connecting an external resistor to the TH pin.
  • Power-on reset delay: The device includes a built-in delay circuit to ensure stable operation during power-up.

Advantages and Disadvantages

Advantages

  • Wide operating voltage range allows compatibility with various systems.
  • Low quiescent current minimizes power consumption, making it suitable for battery-powered applications.
