Overview
The TPS3700DDCT, produced by Texas Instruments, is a wide-supply window voltage detector designed for overvoltage and undervoltage detection. This device operates over a supply voltage range of 1.8 V to 18 V and features two high-accuracy comparators with an internal 400-mV reference. The TPS3700DDCT can be used either as a window voltage detector or as two independent voltage monitors, with the monitored voltages set using external resistors. It 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.
