The BTS737S3 is a dedicated high-side switch that can provide either logic level inputs or advanced diagnostics allowing the user to monitor battery current and voltage.  The switch is typically used for automotive power distribution in battery management applications. It has high-voltage isolation between its input and output, allowing it to be safely used in extremely harsh conditions. In this article, we will discuss the features, applications, and working principle of the BTS737S3.

Features

The BTS737S3 is a high-side switch with several key features:
  • Control input capable of interface with logic-level sources
  • Diagnostic output: Provides low-side current and high-side voltage
  • 1.3µs turn-on/off times: Allows extremely fast switching
  • Vbb range up to 28V: Allows operation in harsh environments
  • High-side isolation up to 2000Vrms: Allows operation in electrically harsh and noisy environments

Applications

The BTS737S3 is typically used for power distribution in automotive battery management applications. It can be used to control the charging and discharge of the battery, while providing diagnostic output that can be used to monitor the battery’s current and voltage.The BTS737S3 can also be used in automotive audio systems, where it can be used to switch between different audio sources. Finally, it can be used in lighting systems to switch between different lighting profiles depending on the time of day.

Working Principle

The BTS737S3 is a high-side switch, meaning it switches the battery’s supply voltage between ground and a higher voltage, depending on the state of the control input. It is capable of switching up to 28V, allowing it to be used in extreme environmental conditions.The BTS737S3 also provides diagnostic output in the form of a voltage and current reading, allowing the user to monitor the state of the battery. This information can be used to ensure proper operation of the system and to determine when the battery needs to be recharged.

Conclusion

The BTS737S3 is a high-side switch designed for automotive power distribution in battery management applications. It is capable of switching up to 28V, providing both logic level inputs and advanced diagnostics. Additionally, it has high-voltage isolation between its inputs and outputs, allowing for safe operation in electrically harsh and noisy environments.
