3 Description

The INA200-Q1, INA201-Q1, and INA202-Q1 (INA20x-Q1) are low- or high-side current-shunt monitors with voltage output. The INA20x-Q1 devices can sense drops across shunts at common-mode voltages from –16 V to +80 V. The INA20x-Q1 are available with three output voltage scales: 20 V/V, 50 V/V, and 100 V/V, with up to a 500-kHz bandwidth.

The INA20x-Q1 also incorporate an open-drain comparator and internal reference that provides a 0.6-V threshold. External dividers set the current trip point. The comparator includes a latching capability, and can be made transparent by grounding (or leaving open) the RESET pin.

The INA20x-Q1 operate from a single 2.7-V to 18-V supply, drawing a maximum of 1800 μA of supply current. These devices are available in the very small VSSOP-8 package. Specifications for all devices extend over the operating temperature range of –40°C to +125°C.
