Overview
The TLV6700DDCT, 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, making it versatile for various power scenarios. It features two high-accuracy comparators with an internal 400-mV reference and two open-drain outputs rated to 18 V. The TLV6700 can be used as either a window comparator or as two independent voltage monitors, making it suitable for overvoltage and undervoltage detection. The device 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.
