(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported.
(2) This voltage may exceed the ratings shown if the current at that pin is limited to 5mA.
DescriptionThe INA200, INA201, and INA202 are high-side current-shunt monitors with voltage output. The INA200−INA202 can sense drops across shunts at common-mode voltages from −16V to 80V. The INA200−INA202 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 1800A 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 to +125.
