The TPS3838K33DBVRG4 is a high-precision voltage supervisor designed by Texas Instruments to ensure reliable operation of microprocessors, microcontrollers, and other voltage-sensitive devices. This device is particularly suitable for battery-powered applications due to its low power consumption and small form factor.

Key Features

• Voltage Threshold: The TPS3838K33DBVRG4 monitors a fixed voltage threshold of 3.3V, which is ideal for 3.3V supply systems, providing an accurate means to detect undervoltage conditions.
• Low Power Consumption: With a quiescent current of only 3 µA (typical), it is optimized for battery-powered and portable applications where power efficiency is crucial.
• Fast Response Time: It features a fast response time, ensuring that the system can react quickly to voltage variations and take necessary actions such as system reset or shutdown.
• Manual Reset: A manual reset input is available, providing a simple way to initiate a system reset independently of the voltage on the monitored supply.
• Low Supply Voltage: The device supports a supply voltage range from 1.1V to 5.5V, accommodating a wide range of applications and making it versatile for different system designs.
• Temperature Range: Operates across a broad temperature range from -40°C to +85°C, ensuring stable performance in diverse environmental conditions.
• Small Form Factor: Supplied in a compact 5-pin SOT-23 package, the TPS3838K33DBVRG4 saves space on the PCB, which is essential for space-constrained applications.

Applications

This voltage supervisor is suitable for a variety of applications, including but not limited to portable electronics, handheld devices, notebooks, and any system where power efficiency and monitoring are critical. It is an excellent choice for designers looking for a reliable solution to protect their systems from undervoltage conditions without compromising on space or power consumption.
