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.

(1) Hysteresis refers to the threshold (the threshold specification applies to a rising edge of a noninverting input) of a falling edge on the noninverting input of the
comparator; refer to Figure 1.
(2) Specified by design.
(3) VID refers to the differential voltage at the comparator inputs.
(4) Open-drain output can be pulled to the range of +2.7V to +18V, regardless of VS.
(5) The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4V.
(6) The RESET input has an internal 2M(typical) pull-down. Leaving RESET open results in a LOW state, with transparent comparator operation.

(1) The INA200, INA201, and INA202 are designed to power-up with the comparator in a defined reset state as long as RESET is open or grounded. The comparator
is in reset as long as the power supply is below the voltage shown here. The comparator assumes a state based on the comparator input above this supply voltage.
If RESET is high at power-up, the comparator output comes up high and requires a reset to assume a low state, if appropriate.
