Overview
The TLV6700DDCR, produced by Texas Instruments, is a high-voltage window comparator designed for a wide range of applications. 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. It is available in Thin SOT-23-6 and leadless WSON-6 packages, both specified over a junction temperature range of –40°C to 125°C. The TLV6700DDCR is versatile, allowing it to be used as either a window comparator or as two independent voltage monitors for overvoltage and undervoltage detection.
