Overview
The TPS37A010122DSKRQ1 is a 65 V input voltage detector produced by Texas Instruments. This device is part of the TPS37-Q1 series, designed for automotive applications with ultra-low quiescent current and time-delay functions. It is capable of monitoring overvoltage (OV) and undervoltage (UV) conditions directly from 12 V or 24 V automotive battery systems. The TPS37-Q1 features an internal resistor divider, which minimizes the total solution size, and offers wide hysteresis voltage options to ignore voltage transients such as cold crank and start-stop conditions.
