TI’s Current-Shunt Monitor Packs Comparators And Reference

\[August 3, 2006\] Housing a high-side, current-sense amplifier, two comparators, and a voltage reference into a compact SO-14 package, the INA206 current-shunt monitor is expected to simplify the design of current-comparison circuits while diminishing the amount of board space needed. The comparators can provide over-/under-current or power supply over-/under-voltage detection. Essentially, two comparators do the work of three as one offers a delay function, useable for a low-level warning output, while the other includes a programmable latch function for higher-level outputs. Both comparators are open-drain output devices with internal 0.6V references with override. The device specifies a common-mode voltage range of -16V to +80V, 500-kHz bandwidth, supply range from 2.7V to 18V, a ±3.5% maximum output error over a temperature range from -40°C to +125°C, and a gain setting of +20 V/V. Two additional factory-trimmed gain settings are expected in the fourth quarter: +50V/V (INA207) and +100V/V (INA208). Available now, price for the INA206 is $1.45 each/1,000.
