Product Overview: TPS3808G01QDVBRQ1 from Texas Instruments

The TPS3808G01QDVBRQ1 is a high-precision programmable delay supervisory circuit designed and manufactured by Texas Instruments. This component is engineered to provide system designers with an effective solution to monitor the supply voltage in microprocessor (μP) and digital systems, ensuring that the system operates reliably within its voltage parameters.

This supervisory IC integrates a voltage monitor with a programmable time delay function, which allows users to set the delay period according to their specific system requirements. It is particularly suitable for use in automotive applications, as indicated by the 'Q1' suffix in its part number, which denotes that the device meets the stringent quality standards required for automotive industry compliance.

The TPS3808G01QDVBRQ1 features a fixed-sense threshold voltage of 2.5V, which is factory-trimmed for high accuracy. Additionally, it offers a low threshold voltage option, providing flexibility for monitoring different voltage rails within a system. The device boasts a low quiescent current, making it an energy-efficient choice for battery-powered applications.

With a wide supply voltage range of 1.7V to 6.5V, the TPS3808G01QDVBRQ1 can cater to a variety of power systems. It also includes a manual reset input, further enhancing its utility by allowing an external signal to initiate a system reset. The supervisory IC is housed in a small 6-pin SOT-23 package, which is ideal for space-constrained applications.

One of the key features of the TPS3808G01QDVBRQ1 is its programmable time delay, which can be set via an external capacitor. This allows designers to tailor the reset assertion time delay to the specific needs of their system, providing additional protection against premature resets due to transient voltage dips.

Overall, the TPS3808G01QDVBRQ1 is a robust and reliable solution for voltage supervision in automotive and other critical applications where precision and programmability are essential. Its combination of features ensures that systems are protected from undervoltage conditions, contributing to the safety and stability of the electronic systems in which it is deployed.
