Window comparator ideal for many applications including Notebook PCs and tablets

The Texas Instruments TLV6700 is a high voltage window comparator that operates over a 1.8V to 18V range. The device has two high-accuracy comparators with an internal 400mV reference and two open-drain outputs rated to 18V. The device can be applied as a window comparator or as two independent comparators; the monitored voltage can be set with external resistors. OUTA is driven low when the voltage at INA+ drops below (VITP – VHYS), and goes high when the voltage returns above the respective threshold (VITP). OUTB is driven low when the voltage at INB– rises above VITP, and goes high when the voltage drops below the respective threshold (VITP – VHYS). Both comparators in the device include built-in hysteresis to reject brief glitches, thereby ensuring stable output operation without false triggering. The device is available in a Thin SOT-23-6 and is specified over the junction temperature range of –40C to 125C.
