The INA200, INA201, and INA202 devices are high-side current-shunt monitors with voltageoutput and integrated comparator. The INA20x devices can sense drops across shunts at common-modevoltages from –16 V to 80 V. The INA20x series is available with three output voltage scales: 20V/V, 50 V/V, and 100 V/V, with a bandwidth up to 500-kHz.
The INA200, INA201, and INA202 devices incorporate an open-drain comparator and internalreference providing a 0.6-V threshold. External dividers set the current trip point. The comparatorincludes a latching capability, that can be made transparent by grounding (or leaving open) theRESET pin.
The INA200, INA201, and INA202 devices operate from a single 2.7-V to 18-V supply,drawing a maximum of 1800 μA of supply current. Package options include the very small VSSOP-8 andthe SOIC-8. All versions are specified over the extended operating temperature range of –40°C to+125°C.
