Overview
The TPS3840PL25DBVRQ1 is a part of the TPS3840-Q1 family of voltage supervisors or reset ICs produced by Texas Instruments. These devices are designed to operate at high voltage levels while maintaining very low quiescent current across the entire VDD and temperature range. They offer a combination of low power consumption, high accuracy, and low propagation delay, making them ideal for automotive and battery-powered or low-power applications.
