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) 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.
