Amplifiers

85 VAEC-Q10016-bit ADCI2Cpower monitorVSSOP-10

INA237AQDGSRQ1 is an automotive AEC-Q100 precision power monitor for shunt-based current, bus voltage, temperature and calculated power measurement on rails up to 85 V.

Best for

  • Automotive high-side or low-side current measurement
  • Battery-management and EV/HEV sensing
  • DC/DC converter and inverter power monitoring

Avoid if

  • The monitored rail can exceed 85 V
  • The required shunt differential voltage exceeds the selected input range
  • A resolved product taxonomy or verified live sourcing data is mandatory

Check before use

  • Program SHUNT_CAL after power-up for current and power reporting.
  • Use 4-wire Kelvin connections to the shunt resistor.
  • Keep input filter resistors at or below 100 Ω when using the recommended input filter approach.
