TPS3809K33DBVR by Texas Instruments

Overview of TPS3809K33DBVR by Texas Instruments

The TPS3809K33DBVR is a 3-pin voltage supervisor, also known as a reset integrated circuit (IC). It features an active-low, push-pull reset output and is housed in a compact 3-SOT-23 package. This voltage supervisor functions effectively within a temperature range of -40 to 85 °C, making it suitable for industrial applications. The primary purpose of this component is to ensure that a system resets properly in the event of voltage drops or other anomalies, which is crucial for the reliable operation of electronic systems.

With a nominal threshold voltage of 2.93 V, it monitors the supply voltage to guarantee that it remains above this value. If the voltage falls below the threshold level, the supervisor generates a reset signal, thus preventing erratic behavior in subsequent circuitry. The TPS3809K33DBVR is classified as a Green, plastic, SOT-23 packaged component, which indicates compliance with environmentally friendly manufacturing standards.

With a supply voltage range of 2 to 6 V and a maximum supply current draw of 25 µA, this part is efficient and suitable for low-power applications. The component has a moisture sensitivity level of 1 and adheres to RoHS compliance requirements, making it a sustainable choice for manufacturers.

Industry Applications for TPS3809K33DBVR

Given its specifications, the TPS3809K33DBVR could find utility across various industries. Below are a few examples of potential applications:

  • Energy and Power Systems: In energy management systems, this voltage supervisor might serve to monitor the output from power sources, ensuring that voltage levels do not fall below acceptable thresholds that could disrupt operations. Related components could include inverters or power converters that require stable voltage levels for efficient performance.
  • Transportation and Logistics: In systems such as fleet management or telematics, the TPS3809K33DBVR could be used to monitor onboard systems. A reset signal can prevent system crashes during transient conditions in vehicle power supplies, enhancing the reliability of communication systems and onboard diagnostics. Components like GPS modules may benefit from this voltage supervision.
  • Renewable Energy: The component might be suitable for photovoltaic systems where voltage stability is critical. The ability to reset under low voltage conditions could protect sensitive equipment, such as charge controllers and inverters, from operating outside their specified voltage ranges.
  • Automotive: If compliant with automotive industry standards, the TPS3809K33DBVR may assist in monitoring various electronic control units (ECUs). In situations where voltage dips occur during cranking or other high-demand scenarios, the reset function could ensure safe operation of critical systems, although compliance with standards like AEC-Q100 would require confirmation.

It is important to note that these industry applications are conceptual and illustrative, requiring further analysis and validation by engineering and design teams to ensure adherence to relevant industry standards and specific application requirements.
