Product Overview: TPS3823-33QDBVRQ1 from Texas Instruments

The TPS3823-33QDBVRQ1 is a highly reliable, automotive-grade supervisor circuit designed and manufactured by Texas Instruments. It is specifically engineered to monitor microprocessor (µP) systems, providing crucial management of power supply and system health. This robust device ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions.

With a nominal voltage of 3.3V, the TPS3823-33QDBVRQ1 is optimized for use in a wide range of automotive applications that require strict adherence to industry standards for performance and reliability. Its features include a manual reset input, allowing for a system reset to be initiated by an external event or user interaction. This is particularly useful in safety-critical automotive systems where manual intervention is necessary.

The device offers a programmable time delay, which provides designers with the flexibility to set the reset activation period according to specific system requirements. This delay ensures that the system has adequate time to stabilize before normal operation commences. The TPS3823-33QDBVRQ1 also includes a watchdog timer, which serves as an independent system monitor. It helps to detect and recover from system malfunctions that could otherwise lead to system failure or unsafe states.

The TPS3823-33QDBVRQ1 is housed in a compact SOT-23-5 package, making it suitable for space-constrained applications. Its small footprint, combined with the low quiescent current, ensures minimal impact on the overall power budget of the system. The device's operating temperature range of -40°C to +125°C allows it to perform reliably under the extreme conditions often encountered in automotive environments.

Texas Instruments' commitment to quality is reflected in the TPS3823-33QDBVRQ1's compliance with automotive industry standards, including qualification in accordance with AEC-Q100. This makes the TPS3823-33QDBVRQ1 an ideal choice for automotive engineers looking for a voltage supervisor that offers both precision and durability in critical applications.

Overall, the TPS3823-33QDBVRQ1 is a testament to Texas Instruments' expertise in creating components that enhance the safety, efficiency, and reliability of automotive electronics.
