current-sense comparatorovercurrent protection36 V common modeopen-drain alertVSSOP-10

INA300AIDGSR is a 36 V common-mode current-sense comparator for fast shunt-based overcurrent detection with configurable delay, hysteresis, and open-drain alert output.

Best for

  • Fast shunt-based overcurrent protection
  • Power supply and battery charger monitoring
  • 36 V common-mode current monitoring

Avoid if

  • Bidirectional current detection is needed from one IC
  • A push-pull alert output is required
  • Continuous monitoring is not needed and enable recovery time is unacceptable

Check before use

  • Set RLIMIT using the internal 20 µA threshold current source
  • Use a pull-up resistor on ALERT
  • Route IN+ and IN- as short Kelvin connections to the shunt
  • Verify the VSSOP footprint and 0.5 mm pin pitch
