The Texas Instruments TPS3128E18DBVR is a versatile supply voltage supervisor IC designed to monitor and manage power rails in electronic systems. It provides essential reset and timing supervision functions, ensuring reliable operation of microprocessors and other sensitive components.
Key electrical characteristics include a supply voltage supervision range of 1.2V to 1.8V, with specific threshold voltages available at 1.14V, 1.43V, 1.62V, and 1.71V (typical). The device features a reset threshold accuracy of 3.7% and a low quiescent current of 0.014mA (typical). The reset output is active-low and open-drain, with a fixed time delay of 180ms. A timeout watchdog timer with a typical period of 1.4 seconds is also integrated, helping to detect system lock-ups.
This supervisor IC supports manual reset input and operates over a wide temperature range of -40°C to 85°C. It is available in a compact SOT-23-5 package, making it suitable for space-constrained applications. The minimum supply voltage is 0.9V, and it can monitor a single voltage supply.
The TPS3128E18DBVR is ideal for applications requiring robust power-on reset generation and system monitoring. Its features make it a suitable choice for embedded systems, portable devices, and industrial control applications where stable power and system integrity are critical.
