LT6703-2/LT6703-3 LT6703HV-2/LT6703HV-3 Micropower, Low Voltage Comparator with 400mV Reference FEATURES DESCRIPTION n Internal 400mV Reference The LT 6703-2/LT6703-3/LT6703HV-2/LT6703HV-3 com- n Total Threshold Error: 1.25% Max at 25C bine a micropower, low voltage comparator with a 400mV n Wide Supply Range: 1.4V to 18V reference in a tiny DFN package. Operating with supplies n Input and Output Operate to 36V from 1.4V up to 18V, these devices draw only 6.5A, making n Speci ed for 40C 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 comparator, ensuring stable operation. n Internal Hysteresis: 6.5mV Typ The comparator has one input available externally while n Low Input Bias Current: 10nA Max the other input is connected internally to the reference. n Over-The-Top Input also Includes Ground The comparator output is open collector and the output n Open-Collector Output Allows Level Translation load can be referred to any voltage up to 18V (36V for n Choice of Input Polarities: LT6703-2/LT6703-3/ LT6703HV) independent of supply voltage. The output LT6703HV-2/LT6703HV-3 stage has a guaranteed current sink capability of more n Available in 2mm 2mm DFN and than 5mA over temperature. Low Pro le (1mm) SOT-23 (ThinSOT) Packages The two versions of this part differ by the polarity of the available comparator input. The LT6703-2/LT6703HV-2 APPLICATIONS has an inverting input and the LT6703-3/LT6703HV-3 has n Battery-Powered System Monitoring a noninverting input. Both versions are offered in com- n Threshold Detectors mercial, industrial and automotive temperature ranges. n Window Comparators L, LT, LTC, LTM, Linear Technology, the Linear logo and Over-The-Top are registered n Relay Driving trademarks of Linear Technology Corporation.
