DESCRIPTION
The 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 1800µA 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.

(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.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
