The TPS3808G33DBVR from Texas Instruments is a highly precise, low-power voltage supervisor designed to monitor 3.3V power rails in various electronic systems. Not only does it feature an ultra-low typical supply current of just 2.4 µA, but it also ensures exceptional accuracy with a ±0.5% threshold tolerance, making it ideal for battery-powered applications where energy efficiency is crucial. Furthermore, its adjustable reset delay, which can be programmed using an external capacitor, allows designers to fine-tune the device’s response time to fit specific application requirements. As a result, it provides enhanced flexibility while also maintaining robust system reliability. Since it operates within a wide voltage range of 1.7V to 6.5V, it is well-suited for microcontroller, DSP, and other low-power system monitoring applications. Additionally, the device’s open-drain, active-low reset output ensures seamless integration with a variety of circuit designs.

Moreover, the TPS3808G33DBVR is housed in a compact SOT-23-6 package, which not only minimizes board space but also facilitates easy PCB layout for space-constrained designs. Because it operates across an extended temperature range of -40°C to +125°C, it can be confidently deployed in both industrial and automotive environments where extreme conditions may be a concern. Additionally, the inclusion of a built-in hysteresis feature ensures noise immunity, further improving system stability. Beyond that, its programmable reset timeout, ranging from 1.25 ms to 10 seconds, provides designers with the ability to tailor the reset behavior to specific timing requirements. Thanks to its combination of ultra-low power consumption, precise voltage detection, and customizable delay, this voltage supervisor serves as an excellent choice for any application requiring reliable power monitoring and fault protection.
