TPS3838E18DBVT - Texas Instruments Voltage Supervisor

The TPS3838E18DBVT is a high-precision voltage supervisor from Texas Instruments designed to maintain system integrity by monitoring the power supply voltage of digital systems. This component is essential in applications that require a reliable operation during various power conditions, ensuring that microprocessors, microcontrollers, and other digital systems reset properly during power-up, power-down, or brown-out conditions.

This voltage supervisor operates over a wide range of supply voltages, from 1.1V to 5.5V, making it versatile for various applications. The TPS3838E18DBVT specifically has a fixed-sense threshold voltage of 1.8V, tailored for systems operating at this voltage level. With a low supply current of only 1.5 µA (typical), it is an energy-efficient choice for battery-operated and portable devices.

One of the key features of the TPS3838E18DBVT is its ultra-small 5-pin SOT-23 package, which is ideal for space-constrained applications. Despite its small size, it packs a powerful punch with its ability to provide a manual reset input and a reset time delay, giving designers control over the reset timing to suit specific system requirements.

The device ensures a robust operation by offering a reset output in both push-pull and open-drain configurations, which can be connected to a variety of digital inputs. The TPS3838E18DBVT is also characterized for operation over a temperature range of –40°C to +85°C, ensuring its reliability in a broad range of environments.

With its precision voltage monitoring and low power consumption, the TPS3838E18DBVT is an excellent choice for applications such as PDAs, portable/battery-powered equipment, smart handheld devices, industrial equipment, and any other systems that require a precise voltage supervisory function to enhance the safety and reliability of the operation.

Overall, the TPS3838E18DBVT by Texas Instruments is a compact, efficient, and reliable solution for modern electronic systems requiring vigilant voltage supervision.
