TPS3851H30EDRBR

The TPS3851H30EDRBR from Texas Instruments is a precision voltage supervisor integrated circuit designed for reliable system monitoring. It combines a high-accuracy comparator with a programmable watchdog timer, ensuring robust performance in demanding applications.

Key electrical specifications include an input voltage range of 1.6V to 6.5V and a precise 0.8% voltage threshold accuracy across a wide operating temperature range of -40°C to 125°C. The device exhibits low quiescent current, typically 10µA, making it suitable for power-sensitive designs. It also features 0.5% hysteresis on the undervoltage threshold and supports common rails from 1.8V to 5.0V.

Packaged in a compact 8-pin VSON (3mm x 3mm) with an exposed pad, the TPS3851H30EDRBR is designed for surface mount applications. It offers an active-low reset with a minimum timeout of 170ms and open-drain or open-collector outputs. The device is suitable for monitoring a single voltage rail and includes features like watchdog disable and a manual reset input.

This supervisor IC is compliant with RoHS3 standards and has an MSL rating of Level 1. Its compact size and reliable performance make it an excellent choice for various industrial and consumer electronics applications requiring precise voltage supervision and system reset.
