Product Overview

The INA209AIPW is a high-side Current Shunt and Power Monitor with an I²C interface. The INA209 monitor both shunt drop and shunt bus voltage. A programmable calibration value, combined with an internal multiplier, enables direct readouts in amperes. An additional multiplying register calculates power in watts. The INA209 features two separate, on board watchdog capabilities of a warning comparator and an over-limit comparator. The warning comparator is useful for monitoring lower warning limits and incorporates user-defined delay. The over-limit comparator assists with monitoring upper limits that could require immediate system shutdown. The INA209 also includes an analog comparator and a programmable digital-to-analog converter (DAC) that combine to provide the fastest possible responses to current overload conditions. The INA209 can be used together with hot swap controllers that already use a current sense resistor.
  • Reports current, voltage and power, stores peaks
  • Senses bus voltages from 0 to +26V
  • Triple watchdog limits - Lower warning with delay, upper over-limit and fast analog critical
  • 1% Maximum over temperature high accuracy
  • 5mA Input current into any pin
  • 10mA Open-drain digital output current
  • Green product and no Sb/Br
