FAQs

What is TPS3808G09DBVT?

The TPS3808G09DBVT is a low-power supply voltage supervisor from Texas Instruments. It is designed to monitor the power supply voltage of a system and provide a reset signal when the voltage falls below a specified threshold. This helps ensure proper system operation and reliability.

How Does TPS3808G09DBVT Work?

The TPS3808G09DBVT works by comparing the monitored supply voltage against a reference voltage. When the supply voltage drops below the preset threshold, the device asserts a reset signal to the system, prompting it to reset or take appropriate action. The supervisor IC helps prevent system malfunction or data corruption due to low voltage conditions.

How Many Pins does TPS3808G09DBVT have and What are the Functions of the Pinout Configuration?

The TPS3808G09DBVT comes in a SOT-23-5 package with 5 pins. The pinout configuration includes:

  • RESET: Output reset signal.
  • MR: Manual reset input.
  • GND: Ground connection.
  • VDD: Supply voltage input.
  • SENSE: Voltage monitoring input.

What are the Pros and Cons of TPS3808G09DBVT?

Pros:

  • Low Power Consumption: Operates with minimal power consumption, suitable for battery-powered devices.
  • Accurate Voltage Monitoring: Provides precise monitoring of supply voltage to prevent system errors.
  • Compact Package: SOT-23-5 package is space-efficient and suitable for small designs.
  • Manual Reset Option: Includes a manual reset input for system flexibility.

Cons:

  • Single Voltage Monitoring: Monitors a single supply voltage, may not be suitable for systems with multiple power rails.
  • Fixed Threshold: The reset threshold is fixed and not adjustable in some applications.

Are There Any Equivalents/Alternatives to TPS3808G09DBVT for Recommendation?

  • The MAX809 from Maxim Integrated is a similar low-power voltage supervisor.
  • Alternatives to the TPS3808G09DBVT include the ADM803 from Analog Devices and the TL7702 from Texas Instruments.
