TPS3803-01MDCKREP TI Supervisory Circuit | SC-70-5 | 1.8V Threshold, Active-Low Reset

Product Overview

The TPS3803-01MDCKREP is a supervisory circuit from Texas Instruments, designed for monitoring power supply voltages in processor-based systems. Housed in a compact SC-70-5 package, this device provides a precision voltage monitor with a fixed threshold of 1.8V. It asserts a reset signal whenever the monitored voltage falls below the threshold, ensuring reliable system operation during power-up, power-down, and brownout conditions. The open-drain active-low reset output remains valid for VDD as low as 1.1V. This enhanced product (EP) is qualified for defense and aerospace applications, offering extended temperature range and reliability.
