TPS3823-50DBVR Introduction

The TPS382x family of supervisors, which includes the TPS3823-50DBVR, is an important part of digital signal processor (DSP) and processor-based systems because it helps with circuit initialization and timing control. This detailed guide aims to explain the TPS3823-50DBVR’s features, functions, and uses so that users can understand how important it is and how to use it to its fullest potential.

Understanding the TPS382x Family

The managers in the TPS382x family are made for DSP and processor-based systems. They help initialize circuits and keep track of timing. They keep an eye on the source voltage, VDD, and don’t turn on the RESET signal until VDD is lower than the threshold voltage, VIT. By slowing the output’s return to the “off” state, an internal timer makes sure that the system is reset correctly. The fixed-sense cutoff voltage, VIT-, is set by an internal voltage divider, so there is no need for extra parts. These supervisors make sure that key systems work well and are easy to build.

Key Features of the TPS3823-50DBVR

  • Made for systems with DSPs and processors: The TPS3823-50DBVR is designed to work with DSP and processor-based devices to supervise and control them.
  • Circuit Initialization and Timing Supervision: It makes sure that circuit initialization and timing supervision are done correctly, which is important for the goal systems to work well.
  • Power-On RESET Signal: The RESET signal is sent when the supply voltage, VDD, goes above 1.1 V during the power-on process. This makes sure that the system starts up in a controlled way.
  • Monitoring voltage and controlling RESET: The supervisor keeps an eye on VDD all the time and keeps the RESET signal low as long as VDD is below the threshold voltage, VIT. This keeps the system stable even when the power source changes.
  • Internal Timer for Resetting the System: The TPS3823-50DBVR has an internal timer that adds a delay before the output goes back to the inactive (high) state. This wait makes sure that the system resets correctly and gives system parts time to settle.
  • Active Output When Voltage Falls: When VDD falls below the cutoff voltage VIT, the supervisor’s output becomes active (low), which means the system is ready to work normally.
  • Simplified planning: The TPS3823-50DBVR doesn’t need any external parts, which speeds up the planning process and cuts down on the number of parts.
  • Fixed-Sense Threshold Voltage: The fixed-sense threshold voltage, VIT-, is set by the boss with an internal voltage divider. This gets rid of the need for external parts and makes it easier to build circuits.
  • Options for Watchdog Timeout: The TPS3823-50DBVR has options for 200 ms (TPS3820) and 1.6 s (TPS3823, TPS3824, and TPS3828) for the watchdog timeout. With these choices, you can change the timeout period to fit your system’s needs.

In short, the TPS3823-50DBVR supervisor helps DSP and processor-based systems with circuit initialization and timing control. It has power-on RESET, voltage monitoring, an internal timer, a simplified design, a fixed-sense threshold voltage, and watchdog timeout choices that can be set by the user. These features help make the chosen systems more reliable and stable.
