Amplifiers

power monitorcurrent senseSPIAEC-Q10085 VVSSOP

INA239AQDGSRQ1 is a 10-pin VSSOP automotive power monitor for bidirectional shunt-current, bus-voltage, power and temperature measurement up to 85 V.

Best for

  • Automotive battery and power monitoring
  • High-side or low-side current sensing
  • EV/HEV and converter monitoring

Avoid if

  • The input differential voltage can exceed ±40 V under fault conditions
  • The application cannot provide accurate Kelvin connections to the shunt

Check before use

  • Shunt resistance and maximum sense voltage
  • ADC conversion, averaging and measurement mode
  • Supply bypassing and SPI interface voltage compatibility
