TPS3899DL20DSER TI Supervisory Circuits | 6-WSON (1.5X1.5) | 2.0V Threshold, Open-Drain Output

Product Overview

The TPS3899DL20DSER 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 2.0V 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 offers an open-drain active-low reset output with a built-in pull-up resistor, ensuring reliable system reset during power-up, power-down, and brown-out conditions. The quiescent current is typically 5µA, making it suitable for battery-powered applications.
