Overview

Category: Integrated Circuits (ICs)

Use: Voltage Supervisors

Characteristics: - Low Power Consumption - Wide Supply Voltage Range - Adjustable Threshold Voltage - Manual Reset Input - Active-Low Push-Pull Output - Small Package Size

Package: SOT-23-6

Essence: The TPS3808G01DRVTG4 is a voltage supervisor IC designed to monitor the power supply voltage of electronic systems and provide reset signals when the voltage falls below a certain threshold.

Packaging/Quantity: The TPS3808G01DRVTG4 is available in tape and reel packaging, with 3000 units per reel.

Specifications

  • Supply Voltage Range: 1.6V to 6.5V
  • Threshold Voltage Options: 1.2V, 1.6V, 2.1V, 2.3V, 2.5V, 2.9V, 3.1V, 3.3V, 3.6V, 4.0V, 4.6V, 5.5V
  • Quiescent Current: 1.5µA (typical)
  • Manual Reset Input Threshold Voltage: 0.4V (typical)
  • Operating Temperature Range: -40°C to +85°C

Pin Configuration

The TPS3808G01DRVTG4 has a six-pin SOT-23 package with the following pin configuration:

  1. GND (Ground)
  2. MR (Manual Reset Input)
  3. VDD (Supply Voltage)
  4. RESET (Reset Output)
  5. GND (Ground)
  6. GND (Ground)

Functional Features

  • Voltage Monitoring: The TPS3808G01DRVTG4 continuously monitors the supply voltage and asserts the reset output when the voltage falls below the programmed threshold.
  • Manual Reset: The manual reset input allows for an external signal to force a reset, regardless of the monitored voltage level.
  • Push-Pull Output: The reset output is an active-low push-pull type, capable of driving both high and low impedance loads.
  • Adjustable Threshold Voltage: The threshold voltage can be adjusted by selecting the appropriate resistor values connected to the VIT+ and VIT- pins.

Advantages

  • Low power consumption makes it suitable for battery-powered applications.
  • Wide supply voltage range allows for compatibility with various systems.
  • Adjustable threshold voltage provides flexibility in voltage monitoring.
  • Small package size enables space-saving designs.

Disadvantages

  • Limited number of threshold voltage options may not meet the specific requirements of all applications.
  • Lack of built-in hysteresis may result in potential oscillations near the threshold voltage.

Working Principles

The TPS3808G01DRVTG4 operates by comparing the supply voltage with a programmable threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted, indicating a power failure or an out-of-range condition. The manual reset input allows for an external signal to override the voltage monitoring and force a reset.

Application Field Plans

The TPS3808G01DRVTG4 is commonly used in various electronic systems where reliable power supply monitoring is critical. Some application fields include:

  1. Microcontrollers and Microprocessors
  2. Industrial Control Systems
  3. Automotive Electronics
  4. Battery-Powered Devices
  5. Communication Equipment
