Overview
The TPS386000RGPR from Texas Instruments is a quad-supply voltage supervisor integrated circuit designed to monitor multiple power rails in various applications. This device is part of the TPS3860x0 family and is housed in a 20-pin VQFN (RGP) package. It features four independent voltage supervisors, each capable of monitoring power rails greater than 0.4 V, with one channel able to monitor voltages less than 0.4 V, including negative voltages. The device offers high threshold accuracy, programmable delay times, and a very low quiescent current, making it suitable for a wide range of applications.
