The INA253 is designed to monitor bi-directional currents over a wide command mode range from –4 V to 80 V, independent of the supply voltage. Three fixed gains are available: 100 mV/A, 200 mV/A, and 400 mV/A. The integration of the precision resistor with a zero-drift chopped amplifier provides calibration equivalent measurement accuracy, ultra- low temperature drift performance of 15 ppm/°C, and an optimized Kelvin layout for the sensing resistor. The INA253 is designed with enhanced PWM rejection circuitry to suppress large (dv/dt) signals to enable real time continuous current measurements. The measurements are critical for in-line current measurements in a motor drive application and for Solenoid valve control applications. This device operates from a single 2.7-V to 5.5-V power supply, drawing a maximum of 3 mA of supply current. All gain versions are specified over the extended operating temperature range (–40°C to 125°C) and are available in an 20-pin TSSOP package.
