Introducing the TPS3802L30DCKR Voltage Supervisor from Texas Instruments

The TPS3802L30DCKR is a high-precision voltage supervisor designed to maintain system integrity by monitoring the supply voltage of digital systems. Manufactured by the renowned semiconductor company Texas Instruments, this device is an essential component for a broad range of applications, including microcontrollers, microprocessors, and DSPs, where reliable voltage monitoring is critical.

Featuring a fixed-sense threshold voltage of 3.0V, the TPS3802L30DCKR ensures that systems operate within their specified voltage range. When the monitored voltage falls below the 3.0V threshold, the device outputs a clear and timely reset signal, which can be used to reset the system to a known state, thereby avoiding any malfunction or data corruption.

The device comes in a compact and robust 5-pin SC-70 package, making it an excellent choice for space-constrained applications. Its small footprint allows for seamless integration into various electronic systems without compromising on performance or reliability.

Key features of the TPS3802L30DCKR include:

• High Accuracy: The device provides a tight threshold accuracy of ±1.5% at room temperature and ±2.5% over the full operating temperature range, ensuring precise voltage monitoring.
• Low Power Consumption: With a very low quiescent current of 9 µA, it is an energy-efficient solution that contributes to the overall power management of the system.
• Manual Reset Input: The inclusion of a manual reset input gives system designers the flexibility to initiate a system reset independently of the voltage monitoring function.
• Power-On Reset Generator: The built-in power-on reset generator ensures that the reset output remains low for a minimum of 200 ms after VDD has risen above the threshold voltage, providing a reliable startup for the system.

The TPS3802L30DCKR is designed for applications that demand high reliability and accuracy in voltage monitoring, such as portable electronics, industrial controls, and computing systems. With its precision and low power consumption, this voltage supervisor from Texas Instruments represents an excellent choice for designers looking to enhance system safety and performance.
