TPS3899DL35DSER TI Supervisory Circuit | 6-WSON (1.5x1.5) | 3.5V Threshold, Active-Low Open-Drain

Product Overview

The TPS3899DL35DSER 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 3.5V and provides an active-low, open-drain reset output. The device is available in a compact 6-pin WSON package (1.5mm x 1.5mm), making it ideal for space-constrained designs. With a typical supply current of only 1.5µA, it is well-suited for battery-powered and portable electronics. The TPS3899DL35DSER ensures reliable system reset during power-up, power-down, and brownout conditions, with a built-in glitch immunity to prevent false triggering.
