TPS3899DL22DSER TI Supervisory Circuits | 6-WSON (1.5X1.5) | 2.25V Threshold, Open-Drain Output

Product Overview

The TPS3899DL22DSER from Texas Instruments is a high-accuracy, low-power supervisory circuit designed for monitoring power supply voltages in a wide range of applications. It features a fixed threshold voltage of 2.25V with a precision of ±0.5% over temperature. The device is available in a compact 6-pin WSON package (1.5mm x 1.5mm), making it ideal for space-constrained designs. It provides an open-drain active-low reset output that remains asserted for a minimum of 200ms after the supply voltage rises above the threshold, ensuring proper system initialization.
