The TPS3840DL31DBVR with Supervisory Circuits Nanopower high-input voltage supervisor with manual reset and programmable-reset time delay 5-SOT-23 from Texas Instruments is an electronic component used in regulating a power supply's voltage. This component is designed to monitor a voltage input range as low as 1V and up to 6V, and is available in a wide range of output types for controlling a variety of system devices. It features a wide array of monitoring, protection, and reset functions, including manual reset input, programmable reset time delay, as well as automatic reset after power-up. In addition, it offers ultra-low quiescent current, integrating both the monitoring and reset functions into a small 5-SOT-23 package configuration for space-saving and cost-effective system design.
