Product Overview

The MAX9019EKA+T is a dual precision nanopower comparator without reference in 8 pin SOT-23 package. It has beyond the rails inputs and operates down to 1.8V. An ultra low supply current of 0.85µA makes the MAX9019 as ideal device for all 2 cell battery monitoring/management applications. The unique design of output stage limits supply current surges while switching which virtually eliminates the supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The MAX9019 has push-pull output stage that sinks and sources current. Large internal output drivers allow rail to rail output swing with loads up to 6mA. It is typically used in ultra low power systems, threshold detectors/discriminators, window detectors, telemetry and remote systems, sensing at ground or supply line.
  • Supply voltage range from 1.8V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Input voltage range extends 200mV beyond the rails
  • Crowbar current free switching
  • No phase reversal for overdriven inputs
  • Internal 4mV hysteresis for clean switching
  • Power supply rejection ratio (PSRR) of 0.1mV/V at VCC = 1.8V to 5.5V
  • High to low propagation delay of 7µs at VCC = 1.8V and 6µs at VCC = 5V
  • Low to high propagation delay of 11µs at VCC = 1.8V and 28µs at VCC = 5V
  • 2-Cell Battery Monitoring/Management; Discriminators; Medical Instruments; Mobile Communications; Notebooks and PDAs;
  • Sensing at Ground or Supply Line; Telemetry and Remote Systems; Threshold Detectors; Ultra-Low Power Systems; Window Detectors
