The INA200, INA201, and INA202 are high-side current-shunt monitors with voltage output. The INA200INA202 can sense drops across shunts at common-mode voltages from 16V to 80V. The INA200INA202 are available with three output voltage scales: 20V/V, 50V/V, and 100V/V, with up to 500kHz bandwidth. The INA200, INA201, and INA202 also incorporate an open-drain comparator and internal reference providing a 0.6V threshold. External dividers are used to set the current trip point. The comparator includes a latching capability, which can be made transparent by grounding (or leaving open) the RESET pin. The INA200, INA201, and INA202 operate from a single +2.7V to +18V supply, drawing a maximum of 1800mA of supply current. Package options include the very small MSOP-8 and the SO-8. All versions are specified over the extended operating temperature range of 40°C to +125°C.
