TPS3899DL15DSER TI Supervisory Circuit | 6-WSON (1.5x1.5) | 1.5V Threshold, Open-Drain Output

Product Overview

The TPS3899DL15DSER 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 1.5V 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 RESET output that remains asserted until the supply voltage returns above the threshold for a specified reset timeout period. The TPS3899DL15DSER consumes only 5µA typical supply current, making it suitable for battery-powered applications.
