DESCRIPTION
The INA206, INA207, and INA208 are a family of
high-side, current-shunt monitors with voltage output, dual
comparators, and voltage reference. The INA206,
INA207, and INA208 can sense drops across shunts at
common-mode voltages from -16V to +80V. The INA206,
INA207, and INA208 are available with three output
voltage scales: 20V/V, 50V/V, and 100V/V, with up to
500kHz bandwidth.
The INA206, INA207, and INA208 also incorporate two
open-drain comparators with internal 0.6V references. On
14-pin versions, the comparator references can be
overridden by external inputs. Comparator 1 includes a
latching capability, and Comparator 2 has a
user-programmable delay on 14-pin versions. 14-pin
versions also provide a 1.2V reference output.
The INA206, INA207, and INA208 operate from a single
+2.7V to +18V supply. They 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) See the Comparator Maximum Input Voltage Range section in the Applications Information.
(4) The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4V.
(5) RESET input has an internal 2M
(typical) pull-down. Leaving RESET open results in a LOW state, with transparent comparator operation.
(6) The Comparator 2 delay applies to both rising and falling edges of the comparator output.

(1) The INA206, INA207, and INA208 are designed to power-up with the comparator in a defined reset state as long as CMP1 RESET is open or
grounded. The comparator will be in reset as long as the power supply is below the voltage shown here. The comparator will assume a state
based on the comparator input above this supply voltage. If CMP1 RESET is high at power-up, the comparator output comes up high and
requires a reset to assume a low state, if appropriate.
