Introduced as a high-side measurement, bi-directional current/power monitor with an I2C interface, the INA209 relies on a zero-drift, auto-zeroing architecture to provides a 1% maximum accuracy over a -40°C to +85°C temperature range with a maximum offset of 100 mV. The device enables monitoring and control of current, voltage, and power in a variety of applications. It monitors the drop across a shunt resistor and senses shunt bus voltage from 0V to 26V. An internal multiplier and calibration register provide direct data for current and power, and the device operates from a single 3V to 5.5V supply. Other features include three levels of programmable watchdogs, full-scale readings as low as ±40 mV, and an external trigger line is available to trigger conversions at specific times. Available now in a TSSOP-16 package, price is $3.50 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
