TPS3899PL31DSER TI Supervisory Circuits | 6-WSON (1.5x1.5) | 3.1V Threshold, Active-Low Open-Drain

Product Overview

The TPS3899PL31DSER from Texas Instruments is a high-accuracy, low-power supervisory circuit designed for monitoring voltage levels in a wide range of applications. It features a fixed threshold voltage of 3.1V 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 active-low, open-drain reset output that remains asserted when VDD is below the threshold and for a fixed timeout period after VDD rises above the threshold. The TPS3899PL31DSER is optimized for low quiescent current (typically 5µA) and operates over a wide supply voltage range of 1.5V to 6.5V.
