TPS3813I50DBVR - Processor Supervisor 2.93V 1 Active Low/Open Drain 5-Pin SOT-23

The TPS3813I50DBVR from Texas Instruments is a highly reliable, low-power processor supervisory circuit designed to monitor system voltages and provide a reset signal to the host processor when necessary. This device ensures that your microprocessor, microcontroller, FPGA, or DSP operates at the correct voltage levels, which is critical for maintaining system stability and performance.

Operating at a nominal threshold voltage of 2.93V, the TPS3813I50DBVR is optimized for systems that require precise voltage monitoring. It is particularly well-suited for battery-operated equipment, portable devices, and other applications where power efficiency is paramount. The device features an active-low, open-drain reset output, which remains asserted until the monitored voltage level rises above the threshold, ensuring that the system has stabilized before allowing the processor to resume operation.

Housed in a compact 5-pin SOT-23 package, the TPS3813I50DBVR is designed for space-constrained applications. Its small footprint is ideal for high-density circuit boards where space is at a premium. The device's low power consumption and wide operating temperature range from -40°C to +85°C make it suitable for a variety of harsh environments and demanding applications.

Key features of the TPS3813I50DBVR include:

• Voltage threshold precision of 2.93V for accurate monitoring
• Low supply current of 9 µA (typical) for power-sensitive applications
• Manual reset input for additional system control
• Power-on reset generator with a fixed delay time of 200 ms (minimum)
• Supply voltage range from 1.1V to 5.5V for versatile use across various platforms

With its robust feature set and Texas Instruments' reputation for quality, the TPS3813I50DBVR is an excellent choice for designers looking to enhance system reliability through effective voltage monitoring and reset management. Whether used in consumer electronics, industrial controls, or computer systems, this supervisory circuit helps maintain the integrity of your digital systems.
