Texas Instruments Inc. has announced a complete comparison soluTIon that combines a high-side current-sense amplifier, two comparators and a voltage reference in a small 14-pin package. TI said the unique integration and functionality of the new device simplifies design of current comparison circuits and reduces application board space. Target applications include computer, power management and automotive systems.

The two uncommitted comparators can be used to provide over-/under-current detection or power supply over-/under-voltage detection. This versatile design allows the two comparators to do the work of three since one offers a delay function that can be used for a low-level warning output while the other comparator has a programmable latch function for higher-level instantaneous critical outputs. Both comparators are open-drain output devices with internal 0.6V references that can be overridden.

The INA206 also features a wide common-mode voltage range of -16-80V, 500kHz bandwidth and a wide supply range of 2.7-18V. It is specified for 3.5 percent maximum output error over the -40C to 125C extended temperature range.

The device offers a gain setting of 20V/V. Two additional factory-trimmed gain setting versions will be available in Q4 2006: 50V/V (INA207) and 100V/V (INA208).

In power management applications, the INA206 is especially suited for use with the TPS2490 hot-swap controller.

The INA206 is available now in a SO-14 package. The device is priced at $1.45 in 1,000-piece quantities. MSOP-10 and TSSOP-14 packages will be available in Q2 2007.
