Product Overview: TPS3838K33DRVT by Texas Instruments

The TPS3838K33DRVT is a high-precision voltage detector designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This component is part of Texas Instruments' extensive family of supervisory circuits that are engineered to monitor power supplies in digital systems. The TPS3838K33DRVT ensures that the system voltage remains within acceptable limits, providing a reliable safeguard against power failures or low voltage conditions.

Operating with a nominal threshold voltage of 3.3V, the TPS3838K33DRVT is particularly suitable for applications that require a precise voltage monitoring solution. This device is capable of detecting overvoltage and undervoltage conditions with a threshold accuracy of 1.5% at 25°C, which is essential for systems that cannot tolerate deviations from specified voltage levels.

The TPS3838K33DRVT comes in a compact, 5-pin SOT-23 package, which is ideal for space-constrained applications. Despite its small size, it packs a powerful punch in terms of performance, featuring a low quiescent current of only 15µA (typical), making it an energy-efficient choice for battery-powered and portable devices.

One of the key features of this voltage detector is its programmable delay time, which allows designers to set the time delay for the reset signal. This flexibility enables the TPS3838K33DRVT to be tailored to specific system requirements, ensuring that devices have adequate time to stabilize before the system resumes operation after a voltage fault condition.

The device also includes a manual reset input, which provides an additional layer of control. By using this input, system designers can implement a manual reset function, allowing users to reset the system as needed without cycling the power supply.

With its wide operating temperature range of -40°C to 85°C, the TPS3838K33DRVT is suited for various industrial and consumer applications. Its robust design ensures reliable operation under adverse conditions, making it a preferred choice for mission-critical systems in sectors such as telecommunications, computing, and medical devices.

In summary, the TPS3838K33DRVT from Texas Instruments is a versatile and precise voltage detector that offers designers an efficient and reliable solution for monitoring system voltages, ensuring the integrity and stability of electronic systems.
