Description
General part information
INA186-Q1 Series
The INA186-Q1 is an automotive, low-power, voltage-output, current-sense amplifier (also called a current-shunt monitor). This device is commonly used for monitoring systems directly connected to an automotive 12-V battery. The INA186-Q1 can sense drops across shunts at common-mode voltages from –0.2 V to +40 V, independent of the supply voltage. In addition, the input pins have an absolute maximum voltage of 42V.
The low input bias current of the INA186-Q1 permits the use of larger current-sense resistors, thus providing accurate current measurements in the microamp range. The low offset voltage of the zero-drift architecture extends the dynamic range of the current measurement. This feature allows for smaller sense resistors with lower power loss, while still providing accurate current measurements.
The INA186-Q1 operates from a single 1.7-V to 5.5-V power supply, and draws a maximum of 90 µA of supply current . Five fixed gain options are available: 25 V/V, 50 V/V, 100 V/V, 200 V/V, or 500 V/V. The device is specified over the operating temperature range of –40°C to +125°C, and offered in SC70, SOT-23 (5), and SOT-23 (8) packages. The SC70 and SOT-23 (DDF) packages supports bidirectional current measurement, whereas the SOT-23 (DBV) only supports current measurement in one direction.
