INA240A1QPWRQ1 provides the 20-V/V automotive INA240-Q1 current-sense function in an eight-pin TSSOP package, changing the board footprint from the SOIC ordering variant.
A shunt may be placed in a path whose common-mode voltage spans -4 to 80 V, so the amplifier can observe current on a motor supply rail without requiring its own supply to track that rail.
Its enhanced PWM rejection attenuates the abrupt common-mode steps generated by inverter switching and helps the downstream ADC receive a stable current signal.
The 2.7-to-5.5-V supply, 20-V/V gain and specified offset establish the analog scaling needed before choosing the shunt and conversion range.
AEC-Q100 Grade 1 coverage and a -40-to-125-degree-C ambient range make the exact QPWRQ1 package option relevant to automotive footprint and temperature review.
