LT6700/LT6700HV Micropower, Low Voltage, Dual Comparator with 400mV Reference FEATURES DESCRIPTION n Internal 400mV Reference The LT 6700/LT6700HV combine two micropower, low n Total Threshold Error: 1.25% Max at 25C voltage comparators with a 400mV reference in a 6-lead n Inputs and Outputs Operate to 36V SOT-23 or tiny DFN package. Operating with supplies from n Wide Supply Range: 1.4V to 18V 1.4V up to 18V, these devices draw only 6.5A, making n Specified for 55C to 125C Temperature Range them ideal for low voltage system monitoring. Hysteresis n Low Quiescent Current: 6.5A Typ at 5V is included in the comparators, easing design requirements n Internal Hysteresis: 6.5mV Typ to insure stable output operation. n Low Input Bias Current: 10nA Max The comparators each have one input available externally n Over-The-Top Input also Includes Ground the other inputs are connected internally to the reference. n Open-Collector Outputs Allow Level Translation The comparator outputs are open collector and the output n Choice of Input Polarities: LT6700-1/LT6700-2/ load can be referred to any voltage up to 18V (36V for LT6700-3/LT6700HV-1/LT6700HV-2/LT6700HV-3 LT6700HV), independent of supply voltage. The output n Available in Low Profile (1mm) SOT-23 (ThinSOT) stage sinking capability is guaranteed to be greater than and 2mm 3mm DFN Packages 5mA over temperature. The three versions of this part differ by the polar- APPLICATIONS ity of the available comparator inputs. The LT6700-1/ n Battery-Powered System Monitoring LT6700HV-1 has one inverting input and one noninvert- n Threshold Detectors ing input, making it suitable for use as a window com- n Window Comparators parator. The LT6700-2/LT6700HV-2 has two inverting n Relay Driving inputs and the LT6700-3/LT6700HV-3 has two nonin- n Industrial Control Systems verting inputs. All versions are offered in commercial, n Handheld Instruments industrial and automotive temperature ranges. n Automotive Monitor and Controls L, LT, LTC, LTM, Linear Technology, the Linear logo and Over-The-Top are registered trademarks and ThinSOT and PowerPath are trademarks of Linear Technology Corporation.
