TPS3840PL43DBVRQ1 TI Supervisory Circuit | SOT-23-5 | 4.3V Threshold, Active Low

Product Overview

The TPS3840PL43DBVRQ1 from Texas Instruments is a high-performance voltage supervisory circuit designed for automotive and industrial applications. It monitors supply voltages and asserts a reset signal when the voltage falls below a factory-trimmed threshold of 4.3V. Housed in a compact SOT-23-5 package, this device offers low quiescent current (typical 1.5µA) and high accuracy (±1% over temperature). It is AEC-Q100 qualified for automotive reliability.
