INA740BIREMR

Chip Resistor - Surface Mount

digital power monitorintegrated shunt85 V monitoringI2CVQFN

INA740BIREMR is a high-voltage digital power monitor for bidirectional current and bus-voltage measurement using an integrated shunt and I2C interface.

Best for

  • High-side or low-side monitoring on power rails up to 85 V
  • Industrial power and battery monitoring

Avoid if

  • The application requires operation outside the -40 °C to 125 °C specified ambient range
  • The required current exceeds the thermal or ADC measurement limits

Check before use

  • Thermal performance at the intended continuous current
  • VQFN land pattern and thermal-pad implementation
  • I2C pull-ups and A0/A1 address connections
