Overview
The TPS3700DSET, produced by Texas Instruments, is a wide-supply window voltage detector designed for overvoltage and undervoltage monitoring. This device operates over a broad voltage range of 1.8 V to 18 V, making it versatile for various applications. It features two high-accuracy comparators with an internal 400-mV reference and two open-drain outputs rated to 18 V. The TPS3700 can be used either as a window voltage detector or as two independent voltage monitors, with the monitored voltages set using external resistors. The device is available in SOT-6 and 1.5-mm × 1.5-mm WSON-6 packages and is specified over a junction temperature range of –40°C to 125°C.
