Automotive Catalog High-Side Measurement Current Shunt Monitor, Current Output
The INA139 and INA169 are high-side, unipolar, current shunt monitors. Wide input common-mode voltage range, high-speed, low quiescent current, and tiny TSSOP-8 packaging enable use in a variety of applications. Input common-mode and power-supply voltages are independent and CAN range from 2.7 V to 40 V for the INA139 and 2.7 V to 60 V for the INA169. Quiescent current is only 60 A, which permits connecting the power supply to either side of the current measurement shunt with minimal error. The device converts a differential input voltage to a current output. This current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100. Although designed for current shunt measurement, the circuit invites creative applications in measurement and level shifting. Both the INA139 and INA169 are available in TSSOP-8 and are specified for the -40C to 125C temperature range.
