TPS3899DL30DSER TI Supervisory Circuits | 6-WSON (1.5X1.5) | 3.0V Threshold, Open-Drain Output

Product Overview

The TPS3899DL30DSER 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 3.0V and provides an open-drain active-low reset output. The device operates over a supply voltage range of 0.7V to 6.0V and consumes only 1.5µA typical quiescent current, making it ideal for battery-powered and portable equipment. The TPS3899DL30DSER comes in a compact 6-pin WSON package (1.5mm x 1.5mm) with a 0.5mm pitch, enabling space-constrained designs.
