TPS3899DL28DSER TI Supervisory Circuits | 6-WSON (1.5X1.5) | 2.8V Threshold, Active-Low Open-Drain

Product Overview

The TPS3899DL28DSER from Texas Instruments is a high-accuracy, low-power supervisory circuit designed for monitoring voltage levels in a wide range of applications. It features a fixed threshold voltage of 2.8V with a precision of 0.5% over temperature. The device provides an active-low, open-drain reset output that remains asserted when VDD is below the threshold and for a programmable delay time after VDD rises above it. Housed in a compact 6-WSON (1.5mm x 1.5mm) package, it is ideal for space-constrained designs.
