TPS3820-33QPDBVRQ1 TI Supervisory Circuit | SOT-23-5 | 2.93V Threshold, 200ms Reset

Product Overview

The TPS3820-33QPDBVRQ1 from Texas Instruments is a supervisory circuit designed for monitoring power supplies in automotive and industrial applications. It provides a precision voltage monitor with a threshold of 2.93V (for 3.3V systems) and a built-in 200ms reset delay. The device is housed in a compact SOT-23-5 package, making it ideal for space-constrained designs. It features an active-low reset output (RST) that remains asserted until the supply voltage stabilizes above the threshold for the delay period. The TPS3820-33QPDBVRQ1 is qualified for automotive applications (AEC-Q100) and operates over a wide temperature range of -40°C to +125°C.
